Thread:Project:Support desk/Cannot upload files since the update from 1.22.7 to 1.23./reply (28)

In principle this does not matter :). The developer team for file management decide to use another basic function to handle the file upload. That some shared host provider think, they can do good things with disable_functions, then we can't, in my opinion, do much things. popen is explained on official php manual (http://www.php.net/manual/de/function.popen.php) without any warning to deactivate or don't use this function. So it is a basic function enabled by default :)

Please ask your host provider, why they deactivate these functions :)
