Hey there!
It sounds like there’s something happening on that edit product page that’s stopping the photo edit function from working correctly.
You may be able to find some hints in the browser console:
Using Your Browser to Diagnose JavaScript Errors
That can point you in the right direction of the name of the plugin (or possibly your theme) that’s causing the trouble.
Otherwise, the next best step is a conflict test to figure out what’s causing the problem. The best way to determine this is to:
- Temporarily switch your theme to Storefront
- Disable all plugins except for WooCommerce
- Repeat the action that is causing the problem
If you’re not seeing the same problem after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated. To figure out which plugin is causing the problem, reactivate your other plugins one by one, testing after each, until you find the one causing conflict. You can find a more detailed explanation on how to do a conflict test here.
