Thread:Project:Support desk/Having trouble running update.php/reply (12)

I have just googled that problem for you.

Here I found one workaround, of which the author says it would be working for him:

cd /home/content/79/9779079/html/wiki/ /usr/local/php5/bin/php maintenance/update.php

No idea, if it works on your hosting package as well.

Another idea: Why do you not run the web updater? You can reach it with your browser by navigating to http://URL-of-your-wiki/mw-config. Or does that in the end internally run a shell command as well?
