UBB.threads PHP Forum Software Community Forums UBB.threads Version 7/8 Support File Attachment Size Problem

It probably is due to your php.ini file has limited it to 1MB
you entered 10 mb.
A quick hint is when setting the file size limit in the ubb control panel there is a note that reads the php.ini file and will state what the max size can be. The attachment size will be the lesser of the two settings.
