Sometimes when I try to access this site I get the error:

Internal error #xp20 (xp#20).

Trying again after a couple of minutes usually succeeds.

Anyone else had this error?

I have not yet experienced that error, but then I access CPP via the legacy interface.

https://legacy.cplusplus.com/forum/

CPP has been an "absentee caretaker" run site for as long as I've been using it, though on rare occasions the admin does do some behind-the-scenes work. The change to the new look vs. the legacy look is one of those occasions.

I am somewhat surprised the site is still up and actively running, at least for the forums. Too bad the email/new user registration feature(s) seem to be disabled.

I have been getting that error message quite often recently. Usually it's enough to just refresh the page once or twice for it to go away.
