I just changed my username (successfully) and then went to change my email address. I received the confirmation email to the new address but I’m getting an HTTP 500 when following the link.
If it doesn’t sort itself out send me a DM and I can tweak it. (I’m not going to debug the forum… hopefully some future upgrade will resolve 
)
Still no joy but it’s not a problem, no need for manual faffing about. Thanks for all the hard work that goes into the software and the many backends!
