Backend Product Display Issue - Help

Version 4.0.3

On the backend after clicking on a product to make changes all that comes up is text as shown in the picture.

I have tried Chrome, IE, and Firefox.

Any ideas?



Are there any custom mods?

Are there any custom mods?

Only a skin that was made by Seonoid a few years back when we upgraded to 4.0.3.

No updates or changes in at least two years.

Well, I need to remember to look at the simple things first. Cleared cache; problem solved.
