Non-Tracked Login Menu Elements on Mobile Version

Hi,

First of all, thanks for the amazing WP theme that you have created.

We have been experiencing a problem with the mobile version of our website. Although the login menu works perfectly on web, on the mobile version only the main page is shown while the rest of the elements are covered in white. The elements are there, yet they are shown within white text color on top of a white background on the mobile. For this reason, the visitors are not able to use the menu on the mobile.

How could we resolve this issue?

Thanks a lot in advance.
