Classic Test Utility 3.3 coughs up the following error for the Directory Permissions and Required File Permissions tests:
"Trying to require ubb_lib.cgi..." is followed by numerous errors ending with "Compilation failed in require at (eval 11) line 1."

Then, the bottom of the page reads:
"The ubb_lib.cgi file was not found or did not load properly. Are you sure that this is the right vars_config.cgi file?"

The Test File/Directory Permissions test shows all is OK.

version UBB.Classic 6.7.0
