I have a VPS and php setting for upload_max_filesize = 4M enough to upload one of my components updates. I have increased, decreased the value, I have noticed in the php.ini the changes but joomla 3.0 is reading 2M regardless.
I found some info here and added an apache code to a .htacces file that previosly saved in the admin folder, but still joomla is reading 2M. I even posted it in joomla.org but no answer.
