Download Manager interfering with Zerif Lite theme mobile menu

Hello!

Thank you for developing such a beautiful plugin.

I have used the Zerif Lite theme in my website. Lately the mobile menu is not working. It is expanding for a split of a second and then retracting again. None of the menu items can be accessed as a result.

I have deactivated all the plugins one by one and found out that when the Download Manager plugin is deactivated, the mobile menu is working just fine.

Can you help me with a solution?

Thanks.
