[edit] MediaWiki Database Support

[edit] (Resolved) Wired Data after upgrading of Debian

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

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

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.

[edit] 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.

[edit] 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.

[edit] Illegal mix of collations for operation after Upgrade

  • MediaWiki: 1.14.0 (upgrade from: 1.3.9)
  • PHP: 5.2.4 (apache2handler)
  • MySQL: 5.1.33-community
  • Url: test-machine @ home (Windows)

Live-Wiki (1.3.9) has charset=iso-8859-1 // (German)

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.

[edit] 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)".

[edit] Update from 1.3.9 (latin1) to 1.15.1 (UTF8) - problem with converting latin to utf8

  • MediaWiki version: upgraded from 1.3.9 to 1.15.1
  • PHP version: 5.x
  • MySQL version: 4.x
  • URL: not public

I make an update via web. After update i have encoding-errors in some (not all!) sections: e.g. Special:ListFiles (Comments), RecentChanges etc. The Main-Content (?title=Mainpage) is ok. No Problems mit Umlauts, Special-Chars. On some pages i get a Collation-Error. (search in ListFiles a Filename with Umlaut) Look @ Database: many Table/Rows has collation latin1 (why?!). I change it manually to utf8-bin/general => collation-errors are fixed. I make a Dump from "images" with mysqldumper (webbased tool), i say his encoding is "latin1". I opened the .sql with notepad++ (windows) and change format from ansi to utf8/boms. Import with mysqldumper. Now: no Encoding-Errors in Special:ListFiles. Fine! Same withe the revision-Table. No Errors in History. Fine! Have I do this with EVERY Table?! :( (49 after update, fresh install 41 ... normal?)

But whats the problem with update-procedure? Only some Tables are converting. Only some rows are utf8 :( How i can update correctly to 1.15.1 utf8 ?. Before update -> dump (latin1) -> convert to utf8 -> import sql -> update? 1-2 Years ago this doesn't work :( Pagenames with Umlauts are broken und many encoding-Errors! :((

Sorry for my bad englisch :( Thanks in advance
