I have JCE Pro installed on about 30 Joomla websites. After updating to JCE 2.7.14 I discovered on one website when I click the File Manager or Image Manager button instead of a modal opening, a small section opens on the same page in the bottom left. What opens is unusable, most of it is off the page. I've only found this on one website, but I haven't tested them all yet.

To troubleshoot this, I disabled the Profile and imported a Profile from another working website. That made no difference.
I also disabled JCH Optimize Pro plugin, and checked if there were any errors in the web dev Console. That didn't reveal anything.
I saw on another forum post it was suggested to disable compression of CSS and Javascript, but those are already disabled.
I tried installing JCE Pro 2.7.14 again but nothing changed.

See this demonstration video = https://cl.ly/ba2faf160354

I'm at a loss on what to try next. Any suggestions?

Thanks,
Richard

I am having the exact same problem after updating also. Need a solution fast...

Chrome browser cache cleared, website cache cleared also - no difference. It still doesn't work.

I reinstalled your new version JCE Pro 2.7.14 from your link, cleared the browser cache. Problem remains.

My admin login has been sent to you. = Thanks!

Thanks, Ryan. I flushed the Cloudflare CDN and all of SiteGround's SuperCacher. It's working now!

I installed the updated plugin and cleared my CDN cache and it solved the problem too. Thanks for the quick fix!:D
