search bar and navigation menu not working

Hi,

After installing this plugin, it has successfully removed the date from the search results. But, since I have installed it, the search bar and navigation has become unresponsive in mobile, working fine in desktop, though. Also, I contacted my theme developer for the same, but they said it has nothing to do with their theme.

Even when I disabled this plugin, those options are working fine. So, only this plugin is causing the issue. Help me, please.
