(Resolved) Wired Data after upgrading of Debian

 * MediaWiki version: 1.11
 * PHP version: 5.2
 * MySQL version: 5.0 / Lastest Debian 5.0
 * URL: http://wiki.seemannsreise.de

After upgrading of debian 5.0 the whole wiki is getting wired. The databases tables itselfes look alright, and instaling a backupdatabase didn't help. What can i do ... ? Richard 212.51.25.1 Update: Upgrading from 1.11 to 1.14 didn't solve the problem.... Update2: Upgrading vom 1.11 to 1.14 with Database Update solved the problem. Everything up and running again :-). See "Upgrading Medawiki" for more information

[Solved] Database error when registered user or Admin try to modify Main page contents

 * MediaWiki version: 1.13.3
 * PHP version: 5
 * MySQL version:
 * URL: http://www.4copter.com/mediawiki

Hello, I have a quite strange problem.

When a logged registered user or logged Admin try to modify the Main page contents he receive an error message: ''Sorry! This site is experiencing technical difficulties. Try waiting a few minutes and reloading. (Can't contact the database server: Unknown error (sql.4copter.com))''

Any non logged user  can modify the main page ! Registered users and Admin when logged can access to their pages.

It is a bug !

'''If I click on the edit link on the left side of the Main page, the hyperlink is something like http://www.mysite.com/mediawiki/index.php?title=main_page&action=edit&section=1

But if I click on the "modify" tab on the top menu of the same page hyperlink is something like http://www.mysite.com/mediawiki/index.php?title=main_page&action=edit

Without the final part of link "&section=1" the page can be modified also by registred user and Admin.


 * Why solved ? where ? I experienced the very same problem.

I will hide editsection until a solution will be found.

ipblocks table corrupt?

 * MediaWiki version: 1.12
 * PHP version: 5.2.4
 * MySQL version: N/A
 * Postgresql version: 8.3.1
 * URL: N/A (intranet)

I receive the following message when trying to describe table ipblocks "ERROR: expected "[" to start datum, but got "4 [ 1 0 0 0 ]})}"; length = 0".

The reason I noticed this is because database dumps are now failing.

Sorry! This site is experiencing technical difficulties.
I get this error when editing any page. But saving a new page is functional.


 * (sitename) has a problem

Sorry! This site is experiencing technical difficulties.

Try waiting a few minutes and reloading.

(Can't contact the database server: Unknown error (mysql6.000webhost.com))

Can any one please help?

Answer: there is a file in the main folder called 'LocalSettings.php'. This file contains your database username and password information. Check to make sure the credentials are correct - this solved my problem. I had a bad password.

Illegal mix of collations for operation after Upgrade
Live-Wiki (1.3.9) has charset=iso-8859-1 // (German)
 * MediaWiki: 1.14.0 (upgrade from: 1.3.9)
 * PHP: 5.2.4 (apache2handler)
 * MySQL: 5.1.33-community
 * Url: test-machine @ home (Windows)

I've got the following error on some pages: ... aus der Funktion „LinkBatch::doQuery“. MySQL meldete den Fehler „1271: Illegal mix of collations for operation ' IN ' (localhost)“.

I've upgraded via Web-Setup. Shell don't work. wgDBmysql5 is true ... false = no error, but i get problem with umlauts like äöü! The complete database has collation binary (manuelly set) and innodb (manuelly). After upgrade is sometimes innodb, myisam mixed or binary, latin1 mixed. I've tested some "install"-methodes (other settings) to upgrade - nothing work :(

What can i do?
 * same problem here :( It seems an issue with moving databases, can't find an easy fix yet.

Database error when trying to edit pages.

 * MediaWiki version: 1.14.0
 * PHP version: 5.3.1 (apache2handler)
 * MySQL version: 5.1.30-log
 * URL: intranet

When trying to update or edit any page, with any user gets 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 "Revision::insertOn". MySQL returned error "1048: Column 'old_text' cannot be null (localhost)". -- I get something similar now, after at least a year of the Wiki working perfectly. Now no writes are possible:

from within function "Revision::insertOn": MySQL returned error "1048: Column 'old_id' cannot be null (..."

This is in MediaWiki 1.15 and PHP 5.2.5.

No changes to code or settings was made between functioning and non-functioning states. However, God knows what the hosting service has done to contribute to this.

Empty database
MediaWiki 	1.15.1 PHP 	5.2.6-1+lenny8 (apache2handler) MySQL 	5.0.51a-24+lenny3

I try to stop apache and export the database at the same time.

I have this error message in my home page :

MediaWiki internal error.

Exception caught inside exception handler

in phpmyadmin, all datatable are present but empty.

in phpmyadmin, I have an error message [in french] : La connexion au "controluser" tel que défini dans votre configuration a échoué.

I try to import a dump I have that error message :

simple PHP query in wikisite, works only in preview mode, after saving I get an error!

Hi, I'll try to make it short! I have installed 2 extensions for the wiki, the first one was: "PHPSecure" and the second one "StubManager" because I will use the Tags in the wiki-site, wich is still a sandbox at the moment. After installation, I added this lines in the LocalSettings.php like in the descriptions: SecurePHP Extension:StubManager

require_once( "$IP/extensions/StubManager/StubManager.php" ); require_once( "$IP/extensions/SecurePHP/SecurePHP.php" ); $wgGroupPermissions['sysop']['bureaucrat']['coding'] = true;

So when I try to make a simple query,like:

require_once "db_mo_con.php";

$sql="SELECT Marke, Preis FROM cigars WHERE id = 1"; $result=mysql_query($sql) or exit("Fehler im SQL-Kommando: $sql"); echo " \n";

then the query works, but only in the preview modus????? When I try to save the page it gives this error:

'''Es ist ein Datenbankfehler aufgetreten. Der Grund kann ein Programmierfehler sein. Die letzte Datenbankabfrage lautete, SQL-Abfrage versteckt aus der Funktion „MediaWikiBagOStuff::_doquery“. Die Datenbank meldete den Fehler „1146: Table 'usr_web433_1.test_objectcache' doesn't exist (localhost)“.'''

wiki tells me that the Table (usr_web433_1.test_....) doesn't exist. this is right, the table doesn't exist, but I didn't ask in the query for this table. And why the query works in preview mode??? Can somebody help me, I'm not a PHP crack, and I'm driving crazy, since 2 days.. it is very strange..

Many thanxs in advance for your Help

Convert From MyISAM to InnoDB

 * MediaWiki version: 1.16beta3
 * PHP version: 5.2.11
 * MySQL version: 5.1.47-log
 * URL: http://ww.softx.tk/

I moved my wiki to another hosting company. The old one doesn't support InnoDB so I have to use MyISAM. The new one does. So I want to convert my database to InnoDB, but how?

Database Error 1205 when accessing a particular Article in my Wiki

 * MediaWiki version: 1.16.0
 * PHP version: 5.2.6 (cgi-fcgi)
 * MySQL version: 5.1.26-rc-5.1.26rc
 * URL: http://konton.us/wiki

Hey there. I installed a copy of mediawiki on my server a couple of days ago and began having fun with my wiki. However, a couple of hours later, something happened with one article I was writing and it seemingly got corrupted. To be precise, I began writing an article, used the preview function several times, had to answer the door and left the computer on for 20+ minutes, then came back, edited some more and clicked 'save changes'. The article did not save and everything slowed down to a crawl. I got so tired of this that I deleted my whole installation and database and tried it all over again. I didn't stumble upon the same error until now, 2 days later. The same thing happened, I was editing an article, I had to go out, came back, changed the text and pressed save again. From the looks of it 'merely my guess', something odd happens with the article updating and the session timeout which 'corrupts' the article. If I wait 5-10 minutes, I can log out and then view ALL other articles, but not the one in question.

After clicking 'save changes', I had a blank page and was then taken to this URL: http://konton.us/w/index.php?title=Gameplay_Mechanics&action=submit

And the error message there was: 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 "Article::updateRevisionOn". Database returned error "1205: Lock wait timeout exceeded; try restarting transaction (internal-db.s76387.gridserver.com)".

So my guess is that...the article became somehow corrupted? How do I uncorrupt it? I googled like crazy and searched everywhere and...I don't seem to be able to find someone with this particular problem =/

All help is appreciated. G.Campos
