Unsupported operand types in adminfunctions_options.php
 

I just upgraded my test site to 3.8.1 PL1 and happened to encounter the above mentioned problem.

If I go to admincp -> vBulletin Options and edit any of the settings, I am able to save my changes without any problem.

However, if I go to admincp -> vBulletin Options -> Show all settings and try to perform a save, I will receive the following error.

Fatal error: Unsupported operand types in /mysite/includes/adminfunctions_options.php on line 692

Any idea what could have went wrong?

Thanks in advance for any help provided.
