Hello,
Maybe you had to add this to the support forum and not rate 1 star right away, but there are a number of reasons the issue you describe could happen.
- Conflicts with 3rd-party plugins, or already have some JS errors in the dev console from other plugins or theme issues.
- Not enough max_execusion time by the server will cause a 500 error which can be debugged with the dev console only.
- I have added a limit of 10 images but sometimes people upload raw images or high quality I have seen images 10, 20, or 30Mb used and loaded on sites.
- There other reasons the but I am unable to do or help you in any way since you just rated 1 star and didn’t send support message.
There are a few other alternatives, search the WP plugins and might have the right one for you.
Thank you,
Krasen
