i had an issue just now that is solved by disabling vbfirewall: with the mod enabled, when i attempt to go to admincp-> vb options -> cookies & http header options i get a white screen and this message: 1||1235333916||||||||Error Opening Logfile. (see post attachment)
On a v3.7.3 system i get this message:
1||1235334329||nnn.nnn.nnn.nnn||do=options&dogroup =http||

Disabling the mod fixes the issue. Tested on two separate v3.8.1 systems and one v3.7.3 system
