Error when updating your profile (08 Sep 2018)
When you try to update your profile, you get an error from the server. This is a know bug, which is caused by incompatibility between the website template software and the forum software. The developers are working on a fix. Hopefully the problem will be fixed before October. Until then please contact a moderator if you need to update your profile. He or she will help you.
