Mobile-Friendly Page

I had an original thread that was eventually closed and ignored with no solution https://kriesi.at/support/topic/mobile-menu-not-consistent-from-page-to-page/#post-735437

Additionally, I tried to install the WPTouch plug-in, and most of my mobile pages showed only source code. Is this theme impossible of being mobile-compatible? I really need an answer to this. Thank you.
