This is because of the updates I am working on (I mentioned this ). I am sorry for the problems, but in a couple of days things will be back to normal
If you are curious: I think the reason for the current login problem is the URL. The SP-Studio main page, the forum, the gallery and everything else is located on my server "planearium.de". The domain sp-studio.de leads to this server, but usually you do not notice this, because only the domain www.sp-studio.de
is shown in your browser. But when I installed the forum & gallery I did not use the correct links in the main menu, that's why "http://www.planearium.de/sp-studio/forum/" was shown in the browser instead of "http://www.sp-studio.de/forum/". I correct this now, but I am not finished yet. The cookies which save your login data might be irritated. So when you cannot log in check the URL in your browser. It should work fine if you always use the old one (http://www.planearium.de/sp-studio/forum/
), so maybe you should bookmark it until I am finished with the website updates.
