I would suggest you move your /mediawiki directory to a mediawiki.old or other temporary location, and just use a fresh extract in /mediawiki

I suspect its an issue with older files that where removed from mediawiki.

Hello,

I was trying to upgrade from v.1.15 to 1.22.

So I download the new MediaWiki archive and inserted the data in the folder to the old 1.15 folder @htdocs/mediawiki

Now when trying to navigate in the browser to the url: http://localhost/smartcards/mw-config/

I will only get the error message : "Fatal error: Cannot redeclare wfProfileIn() (previously declared in C:\xampp\htdocs\smartcards\includes\profiler\Profiler.php:33) in C:\xampp\htdocs\smartcards\includes\ProfilerStub.php on line 24"

Can I get help here please?

Sorry for my English!

Kind regards
