I have upgraded our wiki from 1.15 to latest 1.23 version. All seems fine except for one page. When I try to edit it or open Discussion page for it, I get error message: "A database query error has occurred. This may indicate a bug in the software." The page in question: http://gsbelarus.com/gs/wiki/index.php/Документация._ГИВЦ_Минсельхозпрода
Thanks for reporting this! Please see http://www.mediawiki.org/wiki/Manual:How_to_debug for how to get debugging information (this might end up as a support question on https://www.mediawiki.org/wiki/Project:Support_desk instead, in the end). Also, I don't see such an error on the URL that you have provided...
Oops, you wrote "when you edit it", sorry - can reproduce. In any case, more debugging information is needed.
I can reproduce it every time. Tested in two browsers, in two different networks. Please, try again: 1) Open the page: http://gsbelarus.com/gs/wiki/index.php/Документация._ГИВЦ_Минсельхозпрода 2) Click "Edit" tab. The error message will appear.
There is a debug info I have got: A database query error has occurred. This may indicate a bug in the software.

Did you only upgrade MediaWiki, or also your database backend? :) I assume you use the MySQL backend? > Error: 1267 Illegal mix of collations (utf8_general_ci,IMPLICIT) and > (cp1251_general_ci,COERCIBLE) for operation '=' (localhost) For a similar bug report, see e.g. https://bugzilla.wikimedia.org/show_bug.cgi?id=5620#c3 Other info: http://automatthias.wordpress.com/2008/12/26/fixing-character-sets-in-mysql/ (and http://dev.mysql.com/doc/refman/5.5/en/charset-collate.html for general info).
Andrei: Can you answer comment 5 please?
I had upgraded both, Mediawiki and MySQL. Anyway, I have reverted to 1.19 version. It works fine for me. So, you could close the issue.
Hmm. Alright.
