Hi - Sorry to hear you're running into issues. Not seeing what you do it's hard to offer advice. Just jumped over to classifieds and things appear to be working as I can click to post an ad. The entry screens come up as they should. I stopped there.
With that said I'll offer:
Make sure you're logged into the classifieds section:

There is a help page:

There's also a user 101 page:

Sometimes browsers can cache information that can lead to problems. You could try flushing the cache or restarting the browser. You could also try a different browser to see if it might be an incompatibility issue.
Another option would be to use the "Contact Us" button on the bottom left of a forum page. That'll reach out to the Tech Admins who may be able to offer further advice.
