Forum keeps logging me out and turning back to mobile version

[Kelseaem]

For the past few days every time I go online I have to log in. I have checked the "keep me logged in" button and I use the computer version from my phone (iPhone 6). When I haven't been in the forum for a few minutes I keep getting kicked out and the version keep changing to mobile.
From a page where I'm logged in

I am sent to this page when I try to reply or see a specific topic

(The pictures are from this forum and the other forum I use. The link for there is http://soundofcollapse-rpg.bulgarianforum.net/ )

If I need to give any other details I will, thank you
