first, i think this error msg hasnt todo anything with the firewall! this looks like u changed the /includes/config.php name and/or path!
https://vborg.vbsupport.ru/showthread.php?t=198856 i think u didnt change the xxxxx to the new path/name of your config.php!
u shud post the script!
Code:
Script : Varies Obviously with what the user is trying to do
if u dont do that, noone can help u! vbfirewall is blocking some internous board things like pm in new pop up window - in that pop up window u get the vbfirewall hack attempt message, and thread subscriptions etc.. but u can fix this by configuring the firewall - its hard todo that if u duno anything about it, but its easy if u look over it - easy to understand!
