Hi @albertmc2,
Sorry to hear you’re having issues with Elementor after activating Smush.
There shouldn’t be any conflicts with Smush and Elementor and I’ve tested this on my installation where I was able to use Elementor without any issues while Smush was active.
Could you tell us a bit more info about the issue that you are experiencing, are you unable to start the builder at all, or adding elements is not working, you’re unable to save changes, etc?
Could you open the page where you have this issue, hit F12 on your browser to open the browser console, and tell us if you see any issues there?
Also, can you tell us which version of Smush, Elementor, and WordPress are you using?
If everything is at the latest version and the issue is still there could you please perform a conflict test by disabling all plugins except for Smush and Elementor, switch to the default WP theme, and see if the issue is gone.
If it is, then activate them back one by one until the issue is back which will tell us where the conflict is so we can debug it further.
I suggest doing this test on a staging site or if you don’t have one make sure to have a full backup of the site before performing the test on a live installation.
Cheers,
