New User Name/Password combination

I’ve been a member here since around 2005… Got the notification the site had changed, and made the transition without issues…
I can comment on posts without any issues, but if I try to post about classifieds it’s telling me to enter my User ID and password, but then says my User ID isn’t recogonised…
Any idea how to fix it?

I went in and changed my password, and it’s still not recognising me…
Maybe this is why the Classifieds are so thin these days?
