Thread:Project:Support desk/Cannot upload files since the update from 1.22.7 to 1.23./reply (19)

I haven't looked into it for now, but i'm sure, that popen in 1.27 isn't used for every function, e.g. in file upload required functions. Maybe you never used the functions which uses popen, so you never had problems before. But with the change to MW 1.23 MW require popen for file upload. I'm not sure, if we want to change this, the standard configuration of php.ini has no disabled functions: http://www.php.net//manual/de/ini.core.php
