Please helpw with what this means
 

I just updated to 3.8, ,and the upgrade script went perfectly, and I am in my admin panel, but when I try to open the forum I get this... Please help!

Warning: require_once(/home/p24l3b8d/includes/init.php) [function.require-once]: failed to open stream: No such file or directory in /home/p24l3b8d/public_html/global.php on line 33

Fatal error: require_once() [function.require]: Failed opening required '/home/p24l3b8d/includes/init.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/p24l3b8d/public_html/global.php on line 33

Looks like you removed init.php in order to get rid of the adsense integration lol.

The error means that init.php is missing so upload it in includes/ folder.

Also check your config.php if you have the right info in it.

Did all of that, the init.php is there, and config is exactly as it was with the previous version....

HELP!

The file found "/home/p24l3b8d/public_html/global.php", but is trying to find init.php in "/home/p24l3b8d/includes/init.php" (notice the different directories). Try directly accessing a thread or something, as it maybe that you have a portal modification that is trying to find the file in the wrong directory.

I can not access anyting, although my admin panel works perfectly.

Have you applied any modifications to any files? (Try reuploading all vBulletin files.)
