UBB.threads PHP Forum Software Community Forums UBB.threads 7 Version 7 Support Problem Adding Files

That's where I verified 10 file attachments (total) and 3Mb (2.86 Mb) file size. That doesn't explain why I cannot post a file here for similar reasons. The only difference is that the error message says I'm trying to post a file larger than 1 mb instead of 2.86 mb and that is before I've even selected a file.
Curious.
