It says this in my Admin CP:
If file attachments are enabled in the forum, this dictates how large each file attachment can be. Max size set in php.ini is 2M so you may not exceed this size.
Just to be clear.
PHP.ini has nothing to do with ubbthreads. It is a config file for php. UBB just reads the setting and displays it for you.
Quick note. I looked at bluehost. I assume that is where you are hosted and you should be able to adjust the settings yourself.(From what I can tell)
