No fields show up

Do you have an ad blocker enabled?

I confirm.
There are no ad specific fileds. Even common fileds like Title, Body or Vocabularies are not shown.
What else: form is exactly the same no matter what kind of ad I want to add (no ad type specific fileds).

Sorry for commenting just after previous post.
Here is the screenshot of 'Create Image ad' form.

I don't know if it's important but problem occures only on my upgraded installation (from 5.x).
On clean install everything works just fine.
Maybe there's some cached data I need to flush to get hook_adapi working properly? But where? How?

I tried to completely uninstall ad module, then flushed all caches (using admin_menu link to flush all caches).
After that → install ad from the beginning - no luck.

subscribing - same problem here exactly

OK, I figured it out.
I've disabled delegator module (part of ctools which is needed for panels) and everything works fine now.

Check if you have delegator module enabled? If yes, try disable it and check 'create xx ad' form again.

My work around: use panel nodes instead of panel pages and disable delegator.module :)

Thanks Greggus - I can confirm this worked for me!

i think this can be closed now
