Hello Guys,

Thank you for your valuable suggestions.

I have changed the permission of whole Installation directory to 777 and all folders but the issue is still there.

Regarding /dental-instruments-manufacturers/skin/common_files/lib/jquery.cookie.js , it was 644 before but I have also tried changing it to 777. No change either ways and tabs are still stuck.

Another observation, When I installed x-cart, all folders were 755. Upon finding that VAR, FILES and CATALOG directories should have 777 permission, I made these changes and tabs of Products Detail Page started to appear but those were non-functional. There was no "Active" tab they were also not showing any "hover" effect when hovering mouse upon any of them. Later I applied 777 to all the sub-directories and files under VAR, FILES and CATALOG folders but tabs went back to all expanded state.

As far as I am able to learn, it is partly because of Files Permission but not entirely because of that. CSS and JS compressions are not turned on from the beginning so this couldn't be because of that either.

Let me also mention I have installed x-cart on the same site and everything was working fine. So this cannot be a "bug" but I rather take x-cart is inflexible towards strict server setting.

I am looking forward for further thoughts on that but at the same time, I am highly thankful for your valuable support and attention.
