2.63 Not working with Elementor

I can’t confirm this – I just created an elementor test page and it works fine.

See here: https://wordpress-demo.arnowelzel.de/example-for-elementor/

Can you provide more details about your setup? Maybe there is another plugin which causes a conflict, but Elementor itself works fine with Lightbox with PhotoSwipe.

Yes,it works. But the elamentor (Elementor + CPT) edition does not work.

I have a message :
“The preview could not be loaded
We’re sorry, but something went wrong. Click on ‘Learn more’ and follow each of the steps to quickly solve it.”

What is “Elementor + CPT”? If you talk about custom post types, how did you add them? Without having a test version where I can check what is going wrong, I can’t solve any problem.

The problem is in my theme not in elementor.

Thank you for your help.
