I'm checking that with my admin.
As far as i know, he push the php limit memory from 8 to 12 and things goes better. I'll try to see if a 16 can be done at least to test the issue.
But he says about a PHP limit upload he push it to 4mb but it seams i'm not able to upload more than 3mb.
I have set in the parameters "store files into a directory". But that doesn't help. And in fact i need 7mb and that seam to be a to high limit for my hoster.
Is there any turn around ?
