Thread:Project:Support desk/Cacaophany of failures updating mediawiki from (I think 1.14?) to current./reply

Hi Johs!

The upgrading page, which the support linked you to is exactly the correct page. Follow the descriptions on that page to update MediaWiki.

A few note on your case: Make sure that you have a working backup! If things break, it might be hard to recover, if you have none.

You basically can update to MediaWiki 1.23 in one step - when you upload MediaWiki 1.23 to your server make sure that really all files are present. It e.g. does contain a mw-config/ folder.

The error message you get has already been dealt with here: Thread:Project:Support_desk/PHP_and_Mysql_was_upgraded_on_my_server_and_now_I_get_a_blank_white_page. Answer: Update to the newest MediaWiki version - this one will then also be compatible with PHP 5.3.
