To correct the issue with Lightbox (assuming that is the issue) I modified the jscript_updater.php as follows:
There are two places in the code that check if: (prArr[i] !== null)
I changed these two instances to: (prArr[i] == '')
This seems to work. I have not fully tested all use cases, but so far so good.
Dan, do you foresee any issues with using (prArr[i]=='') in place of (prArr[i]!==null)?
