Limited Support
Our team is currently on holiday, so support will be limited during this period. Response times may be slower than usual, and some inquiries may be delayed.
We appreciate your patience and understanding, and we’ll resume our usual support by the end of August.
The message writing option has stopped working, the cursor does not appear, and the icon menu does not appear. What could be the reason for this?

It seems you've installed a new plugin or updated some plugin which generates JS error on front-end. Please deactivate all recent added/updated plugins, delete all caches and check it.
JS error comes from this code:
Try to use jQuery instead of $
If you want to use $ instead of jQuery all the time you can run your code in a separate, private scope that holds the definition of $ by using a self-invoking function.
(function($){
// your code with $ goes here
})(jQuery);
In any case if you can't fix this JS error, please remove it.
Thank you very much for the help but I do not know how to fix the error. I'm working on it and nothing works for me. 🙁
Have you tried to remove this JS code?
