UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Bug Reports 6.5.2 vs 6.5.4

For some reason it's not able to verify the proper files being uploaded. You can do a pretty quick manual upgrade since there are no database alterations.

Just open up the install/UPGRADE_CHANGES.txt file and make sure you have uploaded all the files listed for version 6.5.3 and 6.5.4
