Issue: Forum Rules

When I click on Forum Rules link (the green one), I get this message:

Warning: array_merge() [function.array-merge]: Argument #1 is not an array in [path]/includes/class_bootstrap.php(1312) : eval()'d code on line 303

The rules load fine after that, but I figured I'd report that since it's a code thing...

I clicked the rules link a few times to see if it was a one-time glitch and got the message every time.
