I’ve been running SP for a couple of months now and there haven’t been any major problems so far. However, the other day I went to change my signature, but on clicking on the profile button I found a blank page. Since then I’ve had reports from users that the same is occurring for them. You can view another’s profile, but the same also happens when I (as an admin) try to edit their profile.
Nothing else seems to have broken anywhere else; all the other functions are working.
