Not that odd, actually it was my bad, after checking Safari options I found a submenu called "advanced options" and two options checked: fixed viewport and constant properties. To be honest I can't remember checking those, I don't even remember having been in that menu before, but I probably did at some point... curiosity killed the cat
It's working fine now and I can see the forum properly, sorry for bothering you with this
