[Solved] Debug output appearing on product screen.

We're getting some script appearing on the product page beneath the tabs.

I looked for a 'display debug' checkbox in system but didn't find one.

Hi again Ian,
This is an outstanding issue on your site. It caused by a third party system plugin that you used? Can you try to disable some third party system plugins on your site and check if which system plugin make this issue?
Thank you!
Sincerely, Giang

OK, will try it without Gantry first...

Ian

I changed the template used by the page from Gantry to Beez5, but still have the same problem.
I am not sure what else to try turning off - we have a number of extensions that are essential - Kunena forum, Phoca Gallery, Watchful plugin.

Any suggestions as to how I could determine which one is the cause?

EDIT: I turned off RokBox plugins that we were using for member login popup, and it now displays correctly.
Problem Solved.

OK That is great.
Please continue to play around with EShop and don't hesitate to let me know if you need any more helps.
Sincerely, Giang
