Given the recent hack, I decided to take the precaution advised in the relevant thread and change my password. Unfortunately, the profile-settings section of the forum is refusing to accept my current password, and thus isn't allowing me to change it.
To be specific: I'm doing this in the "Account Related Settings" section of my profile. I fill in my intended new password, confirm it just below, and at the bottom of the page fill in my current password. When I then click on the button labelled "Change profile" (beside the password field), the page reloads with the following error at the top:
The following errors occurred when trying to save your profile:
The password you entered was not correct.
I'm pretty confident that I am entering my password correctly.
I recall that I actually noticed this shortly after signing up here, but didn't worry too much about it at the time.
I intend to log out and double-check that my password works, and is what I think it to be (i.e. that I haven't been making a mistake in typing my password from first entering it). If I don't return with an edit, something may have gone wrong. ^^;
[edit]
All right, a quick test seems to verify that I do have my password correct--it logs me in--but that same password doesn't work in the "Profile" area. This was tested by copy-pasting the password into the relevant fields.
