I tried to update my installation with ComfortUpdate. It went wel till after step 3. It did not load the page of step 4a , it kept on loading and the page was white. I looked into the troobleshooting pages and found out it probably had to do with the memory of PHP so I enlarged the memory limit. After that I tried logiing in, but I get an error page: HTML ERROR 500. cannot find this error in the manuals or in the other threads. Hope someone can help me out!
