I have just upgraded my MW installation from 1.8.2 to 1.24.1 and now at the top of some pages I am seeing a lot of:
Warning: escapeshellarg() has been disabled for security reasons in /home/smtkwgqq/public_html/wiki/includes/GlobalFunctions.php on line 2714
Does anyone know if MediaWiki has always needed escapeshellarg?
thanks
I don't know, when it was added, but it is always used, when a shell function is executed, so it's essential for all upload actions. Maybe you should ask your provider, why they blocked the access to it :)
There basically are two answers - and neither of them is pleasant: Either the host is unable to create a save setup with such functions enabled so that you should better change your host. The other option is that he wants you to pay additionally for this/these function(s). In this case you might want to change to a more reputable host.
