Thread:Project:Support desk/Upgrade and and Error: invalid magic

Hi everyone. A few minutes ago I tried to upgrade from 1.24 to 1.25 by navigating to /mw-config/, however, when the procedure has to identify the existing version of MediaWiki, I get the following error.

[ad0b6b5c] /jurapedia/mediawiki/mw-config/?page=ExistingWiki MWException from line 337 of /home/cassoc/p03cw4/public_html/mediawiki/includes/MagicWord.php: Error: invalid magic word 'createpage'

Any suggestion?
