Excellent catch for this update. Thanks to your quick work, I kept my site looking good while I can continue to upgrade things out of the public eye for now.

Enabled it fixes all the jquery issues from the update BUT Backend forms are broken.

I download this plugin a few months ago and fixed my wordpress site's issue (photo gallery)...my gallery stopped working recently so I checked this plugin and updated it. That didn't do the trick. I'm running the current version of WordPress, which is 5.6. Any suggestions?

It used to work in it's previous version of 1.2 somewhat ok, albeit slowing down the whole site significantly and with occasional errors (but still better than a broken site after the dropped wordpress jquery support) The newest version of 1.3 breaks the site on its own, might be due to some incompatibility issues with revolution slider, or visual bakery, but graphics are missing and errors are prevalent, again on a significantly slowed down site. Wish they never dropped the jquery support, even with this migration plugin not all plugin developer will update their work, and people will get stuck with broken slowed down sites and issues. Way to go, improvement of the finest.

Perfect Net that saved our Fall Great Job - many thanks Mike

great job with this plugin
