Hello,
You need to find the line using the "split" function and replace it with "explode".
I don't use that extension so I can't tell you exactly how to do it, but usually just replacing the text "split" with "explode" will do the trick.
Here are more information on explode:
www.php.net/manual/en/function.explode.php.
Make sure you have a back-up before modifying anything.
By the way, I hope you know this problem has nothing to do with my extensions.
