Hi,
where does this error display? I checked demo page and it seems fine.
Though last two days I had some problems with ssl certificate on c5center.com.

it does display in the firefox webdesigners tools (inspector) as style warning not able to be loaded on your demo page:https://c5center.com/add-ons/grand-gallery...
Thx

Ok, I think I know what is going on.
It throws errors when image is selected, like:
https://c5center.com/add-ons/grand-gallery#&gid=1&pid=1...
Something must have been changed recently in browsers, it worked earlier.
Anyway I'll fix it tomorrow/on Friday.

In the end it was just an external javascript code on c5center that was causing errors. It should be fixed now.
No fixes needed for Grand Gallery.

Cheers

Ok that's fine thank you!
