this is the text i have at top of my admin panel on left side of vbulletin admin page,
after my partner loaded the shoutbox files. and can no longer access panel, vbulletin is useless right now, is there a fix, or do need to load vbulletin again, or just an upgrade will fix it?

It sounds like a misconfiguration on your server, but if it is caused by an addon/mod then you need to disable all plugins by adding this line to your config.php file
define('DISABLE_HOOKS', true);
If a mod you installed is the problem then this would allow you into the admincp to uninstall the product itself.
