Error Message - Control Panel

[jody108]

When I try to log on to my control panel for 4.0, I get this message:

"Warning: array_keys() [function.array-keys]: The first argument should be an array in [path]/includes/functions.php on line 4918

Warning: Invalid argument supplied for foreach() in [path]/includes/functions.php on line 4918"

Also, my forum post have disappeared.

Can you tell me what is going on? Or some idea?

Try disabling your modifications/plugins and see if you still have this problem.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php

define('DISABLE_HOOKS', true);

If that doesn't fix it, please post on vb.com for help. See this sticky - Installation Issues / Questions or bug reports regarding default vBulletin 4.0 (https://vborg.vbsupport.ru/showthread.php?t=228035)
