Guys, how to make the site display the same content on all devices?

Question

CMS

The essence of the problem: The site is written on a template, Joomla cms, everything is displayed correctly from a PC, but as soon as you log in from your phone / tablet, the site becomes mixed with the standard template data. Link www.northview.ru
ps The site is still under construction, so do not judge strictly.

Answer 1

I came from the phone, I do not observe any crime. What is the "standard template data", explain. Attach screenshots.
Yes, and clear the browser cache on your phone / tablet, and do it constantly until you finish working on the site. Mobile browsers are very fond of displaying cached (and therefore irrelevant) content and are very reluctant to part with it.
