Response design menu button does not work

I've noticed today that the menu button on the mobile version of my forum does not work. I want to find out what happened. My forum is pointed at http://e-knigi.club . Can someone help me out, please?

Are you using a custom theme?

Nope - I'm using the default persona theme....

@nullcx it's an issue with the ads on your theme. ads section is interfering with the navbar.
