Whenever I try to click on the editor button inside of an article I get the following error. "The requested content cannot be loaded.Please try again later." I am on both the newest version of joomla 3.9.11 and the newest version of the extension 3.6.7. I have even tried uninstalling the previous version of the pluign and reinstalling from scratch and the issue still happens. I am not really sure what is going on here?

Joomla version 3.9.11
Simple Image gallery pro 3.6.7
PHP version 7.1.32

Thanks,

Josh

I was able to figure out what was going on . 2 different versions of fancybox were loading in the admin. I had a custom admin template and for some reason v2 of fancybox was loading at the same time as version 3 no idea why. I deleted the old version of fancybox out of the admin template and it fixed it.
