I have the same issue as the one here: CiviEvent - Error when registering: Could not find valid value for id However the solution mentioned does not work for me. Besides on the demo site http://wpmaster.demo.civicrm.org/ no base page is set and it works. Any help is greatly appreciated.
I'm on WP 4.4.2, civi 4.7.7
The error from the log is below:
May 20 10:06:31 [info] $Fatal Error Details = Array
