That says you are not using a user account that is an simple press admin… remember, wordpress admins are not simple press admins…

log in via a simple press admin and on forum – admins – manage admins, you can add more users as simple press admins if you want…

Thanks, but how do I log in as admin then?
I can not find it. Is it through a URL?

I am an administrator.

you are still confusing wordpress admins with simple press admins… they are NOT the same…  any user can be a simple press admin but not be a wordpress admin…  this allows ordinary users to be a simple press admin, but not have any wp admin rights or access…

at install, only the wordpress administrator who installed simple press is a simple press admin..  as stated before, that simple press admin can make any other wp user be a simple press admin (but not be a wordpress admin)…  that original simple press admin can add more simple press admins on forum – admins – manage admins…

so go back and log in as the wordpress admin who installed simple press and add this other user account as a simple press admin…

Thanks for your cooperation. Problem is solved.

np… glad to help!
