endless download of mega-menus

Hi,

This problem can be from the firewall or security module which blocks admin-ajax.php request. Please verify the console for error while saving the settings on the Theme Panel, usually, it displays a 403 or 404 error.
If you don’t use a security plugin, please ask your host about this, maybe you have a security module which blocks this.
If you use a plugin like Wordfence please set it in learning mode.
Also, make sure that you do not have a plugin conflict, please deactivate ALL plugins except tagDiv plugins, also if you are using a child theme or cache plugin, deactivate them, clear all cache and try again.

Hope this will help you!

Thank you!
