Hello all, first thx for reading this

Ok here is my prob :
I can upload large files from the local network to my SME box (server&gateway mode) using the file manager of egroupware (therefor I changed the PostMaxSize and UploadMaxFilesize of the php.ini with db commands). But when I try to do upload another large file from the internet I have a popup saying "page contains no data" and no damned file
thought I can upload files from internet, but no bigger than 1 Mb, and I didn't see this limit anywhere...
Please help me to solve this one, I realy need to upload more than 1Mb.
Thank you in advance
