After activating I get the console error

Uncaught TypeError: jQuery(…).live is not a function

Nothing requiring js works any more in the backend

I had to deactivate it.

I also tried the fix suggested here
https://toolset.com/forums/topic/uncaught-typeerror-jquery-live-is-not-a-function/

wp_enqueue_script( 'jquery-migrate' );

But it didn’t help.

Initially thank you very much for your efforts
The addition is perfect and needs some development, but after I used it I stopped it because of the inability to adjust settings on the mobile when I try to land unfortunately it does not interact with the screen unfortunately and I hope to adjust the font size.
Thank you in advance
