Hi

I recently upgraded from version 1.22 to 1.25. Every page now returns the error:

Fatal error: Call to a member function setPageTitle() on a non-object in /wiki/includes/page/Article.php on line 512

and special pages the error:

Fatal error: Call to a member function setArticleRelated() on a non-object in /wiki/includes/specialpage/SpecialPage.php on line 353

Unusually, Google returns nothing on the subject, which suggests this is a unique error - which is itself surprising as the upgrade was smooth.

Any help would be appreciated.

Did you upgraded your extensions as well? This looks like it's being caused by one of your installed extensions. The extension may not be compatible with MediaWiki 1.25

If you've updated all extensions, too, check, if you transferred all files of the new MediaWiki version to the server, correctly.
