Hi @Advasa,
I checked your website and the mobile menu is working with no problem for me. What you have described is a typical problem of Javascript error. If there is a Javascript error which prevents the browser to continue running the code, all other Javascript related animations such as the mobile menu or accordions will stop working.
That was the case for you it seems, but at the moment I checked the website with my browser and check the Javascript console and there is no Javascript error. So whatever was that it is fixed.
I suggest that you clear your browser cache or check the website with another machine.
If you still have problems we will appreciate that you get back to us with the URL/User/Pass of your website using the secure note to follow up.
Thank you.
