I just upgraded to version 6.1.0 of UBB and everything works fine except that I can't delete or close any topics. I always get the following error:
Can't obtain exclusive lock: Permission denied at /web/sites/170/xheviax/www.nefertem.f2s.com/cgi-bin/ubb_lib_files.cgi line 565.
I tried re-upping the original file from the upgrade byt it keeps giving yhe same error and the file is not used in any hack I have installed.
