Found the problem! It was so simple I cant believe I lost hours looking for the solution.
I just had to comment the line:
Code:
define('USE_ADMINCP_BRIDGE', true);
According to the Installation instructions this line is supposed to be commented by default but in fact it isn't.
I will be testing your wonderful plugin in the next hours but for now its working great. I am just missing one thing, the avatars are not showing in Wordpress.
Thank you very much Jeff
