UBB.threads PHP Forum Software Community Forums UBB.threads Version 7/8 Support .pdf errors

I am getting .pdf error msg on any .pdf file I try to post.




(pdf location) http://forums.falconeasygroup.com/ubbthreads.php?ubb=showflat&Number=1709#Post1709

I have the admin set for post files and the max file size 2097152 and change the settings to accept .pdf.

The file works normaly, prior to me uploading

Any Ideas
