Error in PhpDig_Functions - Line 194

[BobH]

I recently installed PhpDig and was hoping to use it on my production site.

But now that I go back to it I keep getting this error message:

Warning: Invalid argument supplied for foreach() in /home/.../phpdig/libs/phpdig_functions.php on line 194

So I can't search, update index ... anything!

HELP!

So, I tried a simple search form ... copied & pasted straight from this site.

Posted my query to the search page and didn't get anything but a blank screen back.

Please help! :no:
