Hello,

Most of these problems are general WordPress problems. As we can see, problems related to our theme are connected to the main loop and menu. Both menus and main loop use standard WordPress posts queries. Usually, it happens when your database is overloaded and your server can’t handle it. Your mobile menu has a lot of links and, in WordPress, each link is a separate post. So loading a lot of posts seems to take a lot of time on your environment. But it is not something that we really can fix in our theme.

Kind Regards
