Attachment problem

[محروم.كوم]

I have a strange problem in the forum i manage. Even though the file limits is set high enough I seem to have a limit somewhere between 3.57-3.69 mb. I can upload the 3.57 mb file but not the 3.69 mb file. The limit is set as 5 mb and it doesn't matter what file type I try. The attachment screen just turns white on Firefox and says that the page cannot be shown in Internet Explorer. The attachments is saved in the database.


Anyone have any ideas what might cause this? __DEFINE_LIKE_SHARE__
