This is a common issue, many users using SSL can come across. The theme uses function “get_template_directory_uri()” to generate the links, so there isn’t a specific file i can show you, where you could change these two urls. I suggest you to refer to this article regarding it. Or install a plugin that does the job. I can suggest you these “Wp Force SSL” or “WordPress Https”

I could open the mobile menu without problem (screenshot) did you manage to fix your issue?
The js error is caused by the js code you have added at your “Custom JS Code”. If you remove it, the error goes too.
