(RESOLVED) Wiki Encoding Problem

 * MediaWiki: 1.11.0
 * PHP: 5.2.3 (cgi-fcgi)
 * MySQL: 5.0.37-community-nt
 * URL: http://wiki.myelectrical.com/

I have had a wiki up and running for a year or so without problems. Recently I have just moved to Dubai and when I first tried the wiki here I received the following error (on some pages only):

''Content Encoding Error (content_encoding_error) Server response could not be decoded using encoding type returned by server. This is typically caused by a Web Site presenting a content encoding header of one type, and then encoding the data differently. For assistance, contact your network support team.''

The wiki was fully functional before I arrived in Dubai (and may still be in other countries). After further investigation I found that the wiki is functional except for certain pages:


 * http://wiki.myelectrical.com
 * http://wiki.myelectrical.com/index.php
 * http://wiki.myelectrical.com/index.php?title=Special:Random
 * http://wiki.myelectrical.com/index.php?search=iec
 * etc.

Example working pages are:
 * http://wiki.myelectrical.com/index.php?title=Main_Page
 * http://wiki.myelectrical.com/index.php?title=Special:Recentchanges
 * http://wiki.myelectrical.com/index.php?title=CT_Dimensioning

... most article pages seem to be working

http://wiki.myelectrical.com/index.php?xx (where xx can be a lot of things)

etc.

I've tried quite a lot of things to resolve this without success. Any suggestions/help would be much appreciated.

 * The non-working pages are now working. -PatPeter, [[Image:Tournesol.png|20px]] MediaWiki Support Team  21:09, 27 February 2008 (UTC)

Peter, the pages are only working in some countries (for example I know they are working in the US). I'm here in the UAE and they are still not working. It appears to be pages that redirect to other pages that do not work (wiki.myelectrical.com and special:random for example). Other mediawiki sites work here in the UAE and I have used the same notebook here and in the US (so firewalls/IE settings would not appear the be the problem).


 * Huh... didn't get that part ok. First of all could you sign your posts with ? My geography knowledge is... well... horrible, so does where ever you are use Latin characters in their language? -PatPeter, [[Image:Tournesol.png|20px]] MediaWiki Support Team  21:07, 28 February 2008 (UTC)

Peter, I'm quite new here in the UAE and I'm not sure if they use Latin or not. If you know of some testing I could carry out to see if things are affected by this please let me know., Steven  62.140.211.130 05:03, 3 March 2008 (UTC)


 * UAE? -PatPeter, [[Image:Tournesol.png|20px]] MediaWiki Support Team  04:43, 6 March 2008 (UTC)

UAE - United Arab Emirates. Anyhow for some strange reason things started working today. I've marked the issue as resolved and will remove the resolve if it happens again. 62.140.211.130

(OUTDATED) Long String of Numbers after moving Wiki

 * MediaWiki: (Reported by your Wiki's Special:Version page)
 * PHP:
 * MySQL:
 * URL:

My company has an internal wiki which we use for internal standardization. We just recently moved the wiki from one box to a newer more up to date box. I did a SQL Dump of the database, recreated the username with all the permssions, copied the Wiki directory to the new box, everything seemed to go smoothly but then when I opened the main page in the content area there is a long string of number of letters. This is on every page. I have no idea where to trouble shoot on this. Any help would be greatly appreciated.

(RESOLVED) Rename user using SQL

 * MediaWiki: 1.7.1
 * PHP: 5.2.0-8+etch10 (apache2handler)
 * MySQL: 5.0.32-Debian_7etch5-log
 * URL: RISE

I renamed a user using the SQL instructions in MediaWiki FAQ (See But can I rename the user, then?). But MySQL complains: ERROR 1146 (42S02) at line 3: Table 'mediawiki.cur' doesn't exist (mediawiki is the name of the database). Kindly help.

(RESOLVED) Delete history
Hello! Is there a way to delete the history of an article in my wiki? So often I change an article so longer will be the list of the versions. Isn't it space on my disc, if there are so many versions to an article in my wiki? So I want to delete the history time to time, but how? Thank you for your replies, Doc Taxon 17:22, 27 March 2008 (UTC)
 * Are you using compression? Aaron 11:50, 28 March 2008 (UTC)
 * I do not know, whether I am using compression. How can I find out? Doc Taxon 15:01, 28 March 2008 (UTC)

There are php scripts you can use to delete the whole history of old revisions for the entire database. Log in as root and follow these steps: 1) Change into your mediawiki directory on your server.  2) Now you can see a directory named "maintenance". Change into this directory. 3) use the command : php deleteOldRevisions.php --delete  4) If it works, you're done. There is only one version of every page left now. If it does not work, you have not specified the necessary database access in the file AdminSettings.php If you don't even have this file, make a copy of AdminSettings.sample and change admin name and password. Go back to 3)

(RESOLVED) "DB connection error" when trying to run the maintenance script "rebuildall.php" (using PostgreSQL)

 * MediaWiki: 1.12.0
 * PHP: 5.2.0-8+etch11 (apache2handler)
 * PostgreSQL: PostgreSQL 8.1.11 on i486-pc-linux-gnu, compiled by GCC cc (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)
 * URL: david.theparticulars.org/wiki/

I used the mediawiki for e few weeks right now and everything worked okay. Now I wanted to try to use a maintenance script for the first time - so I insertet into the AdminSettings.php the same username and password for the PostgreSQL-Server as in the LocalSettings.php. With exactly this username and password, I can log in on the PostgreSQL-Server from the shell (using the command-line tool psql...). But when I run the script rebuildall.php, it keeps saying: "DB connection error: Access denied for user '(...)'@'localhost' (using password: YES) (localhost)". Even with a newly created superuser for PostgreSQL, with which I can log in from the shell and who's data I inserted into the AdminSettings.php, it does not work. Do you have any suggestions? Thanks you.

(RESOLVED) Can't get past the "Could not find a suitable database driver!" message.

 * MediaWiki: (Reported by your Wiki's MediaWiki 1.12.0 Installation page)
 * PHP: 5.2.6
 * MySQL: 5.0
 * URL: http://localhost/mediawiki-1.12.0/config/index.php

This is what I get - it's our old facourite:
 * PHP 5.2.6 installed Could not find a suitable database driver!
 * For MySQL, compile PHP using --with-mysql, or install the mysql.so module
 * For PostgreSQL, compile PHP using --with-pgsql, or install the pgsql.so module

Bear with me, I'm a newbie at wiki work.

I'm trying to install MediaWiki onto a Vista PC. (I know I ought to be using Linux but there have been problems - another long story.)

I installed MySQL some time ago into C:\Program Files\MySQL\MySQL Server 5.0 and I have been using it fairly successfully with Java apps developed in Eclipse, so I'm fairly sure that's all right. Yes, it is configured as "root" and uses port 3306, as it should.

I had bad experiences with various Wamp packages, mainly because there were problems with the MySQL installation. XAMPP was worst. So I decided to go with the manual downloads.

Apache 2.2.9 is installed in C:\Program Files\Apache Software Foundation\Apache2.2 and configured to work on port 80.

PHP is installed in C:\PHP\php-5.2.6-Win32 and it has been configured as per the instructions.

I have ensured that all DLLs are in the \ext directory of the PHP installation.

I have added ";C:\PHP\php-5.2.6-Win32" to my path file and made sure it occurs BEFORE the one for MySQL (I'm up to speed on environment variables, I use this technique all the time in the day job). The point about it being before the MySQL entry is in response to something I read on another help page.

I have made sure that the php_mysql.dll and php_mysqli.dll entries are uncommented out of the php.ini file so as to enable them.

I have made sure that the line extension_dir="C:\PHP\php-5.6.2-Win32\ext" is in the php.ini file.

I have copied the libmysql.dll, php_mysql.dll and php_mysqli.dll files have been copied into the Apache2.2\bin directory (again in response to a comment on a help forum).

PHP works, I've tested that. Apache works (eventually), I tested that. (If they didn't I wouldn't have got this far.)

I've scoured all the help forums I can find and applied all the solutions I've been offered, but I still get the pesky page:

MediaWiki 1.12.0 Installation

Don't forget security updates! Keep an eye on the low-traffic release announcements mailing list.

Checking environment...

Please include all of the lines below when reporting installation problems.


 * PHP 5.2.6 installed Could not find a suitable database driver!
 * For MySQL, compile PHP using --with-mysql, or install the mysql.so module
 * For PostgreSQL, compile PHP using --with-pgsql, or install the pgsql.so module


 * SORTED IT ...
 * It was me being silly. Although I'd put my PHP stuff into C:\PHP\php-5.2.6-Win32, in the php.ini I was actually invoking the extension directory as C:\PHP\php-5.6.2-Win32.
 * I found this by finding and checking the Apache error log. I also found I was invoking a dll that it couldn't invoke (which I didn't need) so I got rid of that and now I'm up and running.
 * Apologies for bothering you, but might be worth leaving this post up in case someone else gets the same trouble.

 * MySQL: version 4

(RESOLVED) mysql database error 1146

 * MediaWiki: 1.12.0
 * PHP: 5.2.6
 * MySQL: 5.0.45
 * URL: http://csdms.colorado.edu

Hi all, I just did a wiki upgrade 1.11.0 -> 1.12.0, all according to the upgrade help page. The upgrade went pretty smooth but I'm facing some errors now. When I try to create any template it will give me the following error:

Database error

A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:

(SQL query hidden)

from within function "Database::select". MySQL returned error "1146: Table 'wikidb.mw_protected_titles' doesn't exist (localhost)".

Any idea how I can get ride of that error message? Thanks in advance, Albert.

 * Solved. I forgot to ran the 'update script'. /maintenance/update.php. That did the trick.--Albert Ke 18:04, 26 August 2008 (UTC)
