Hi @ettoregabrielli,

Could you try installing and activating this plugin: ​https://wordpress.org/plugins/enable-jquery-migrate-helper/.

This will confirm that there is JavaScript on your site that needs to be updated to follow more modern jQuery practices. You can leave the plugin active for the time being, but it will not fix the source of your problem and the breaking code will need to be updated before the next step of the Upgrading jQuery in Core roadmap.

If the plugin does fix your issue, then please reach out to the plugins and themes that contain the old code directly (the warnings and notices that are triggered should will be displayed in your dashboard).

I'm marking this as a close candidate as I am fairly confident this is the source of the issues you are seeing and would make this not a WP Core issue.

I try J-Query Migrate but i don't see errors about comments, but commenst doesn't show out.

I think that the changes associated with the following ticket may be causing the issue within your theme: #49236.

I recommend that you reach out to them directly to report the issue.
