Ahhh I just solved it.
I had to set Z-Index to a super big number because the error pops up at the top but we have a fixed header that scrolls.
After setting it to 999999999999999999999999 which is way larger than the largest valid number. It works.
Try that and look for the little error message in red at the top of your browser.
I am getting the same thing. The error is not displaying in a pop up. I can see it in firebug but nothing shows on the page.
Any recommendations?
