I noticed that two functions of this forum don't work, at least not for me. After I registered I could use them for a while but now they only give me an error. The two functions are "Show new posts since last visit" and "Mark all as read". When I try using I only get "There are no results for your search." for the new posts and "The link you are trying to reach is no longer available or is invalid. " for the mark all as read. I noticed this behavior a few days ago on my PC, my mobile phone, my tablet and my work PC. I am using Chrome on all of them and it could be that is only a problem with Chrome but it did work at first. I did test it with IE, didn't work there either but that could just be IE. Also the redirection when logging in does not work but I don't mind that one so much.
I do know that this is an old forum which doesn't really get updates anymore but it's something that shoud still work and was still working not to long ago, I'm only a member for 3 weeks at max so it's really not that long.
