Replying to Problems with the new site

When I post a message in the forums, I click reply then it just brings me to a blank white page(I waited like 10 minutes and nothing happens) and then I have to press back, then like 3 minutes later my post pops up

And also, when I want to go to a new page of forums like the main ones on top (main forums, regional, cult...) I click on something then it just brings me to a blank page again. then I have to press back, click on another thing in the quick links, then I when I go back to the page where you select the forum, it is at the place where I clicked previously that brought me to a blank page... I dont know if you get this, hahah
