[RN BB guy]

I tried to install chat box and i got this?

Warning: chmod(): Operation not permitted in /home/nurses/public_html/forum/admin/chatbox_install.php on line 65


I did the chmod and changed 775 to 777. It completes the installation but i cant find it in cpanel

in the box below of the warning is this:

Database error in vBulletin Control Panel 2.3.4:
