I have a several plugins that are required and cannot be disabled. I disabled or deleted any unnecessary plugins and it’s still not working.
I have multiple sites using this theme, each on has it’s own license.
The first site was built and this feature worked fine. I then cloned the site, de-activated the theme license and re-activated it with the updated license. The second and third site are both experiencing this issue with slides where you cannot upload a new graphic. There’s an image there from the clone, but when you try and update the graphic you can’t.
