My file uploads fail in the front end and back if they are to big. I am able to upload large files to Easysocial but not Jdownloads. I've looked every where i can think PHP.ini, configuration files for jdownloads and system settings in Joomla. I cant seem to find it it's probably me and i've looked over it. The front end gives a 404 not found error.
Also when the file is small and it is a *.exe it will not accept it.
