What the heck??? Help

Today I visited the site and found I had been logged out, so I logged in. Once I logged in I found a format that I am not used too and I don't like it, I cant see any member info except their user name, there are now ads in the middle of threads that were not there just yesterday, and much more.

I tried finding a different format button and it only says desktop view but changes nothing. I cant edit my profile, my signature, see my friends list, my message history, my posts have no signature, or anything. I've been a member here, although not contributing, since 2014 and now all of the sudden something is different, what gives?
This is one of my favorite sites!

Let's block ads! (Why?)

What the heck??? Help
