OK, but sorry my google english )
There is a page designed for a group of users - http://expertbaby.ru/nashi-kursyi/sekretyi-vospitaniya-otvetstvennogo-rebenka/
(By the way, here is protected only by the main text, but not the sidebar, and it may be unique for this page.)
Here, the page where I need to redirect unauthorized user - http://expertbaby.ru/blockedpage/.
Now everything is set up that way, but as you can see, nothing works.
And no matter what the settings are set to Redirect User. Does not work redirect to the home page or a custom page or a custom URL.
I read somewhere and tried to fix for an experiment - line 298 of user-access-manager.php:
add_action ('template_redirect', array ($oUserAccessManager, 'redirect'), 10);
the redirection works, but found a problem with a page templates - always use a basic template, regardless of the selected template of the page.
In all other respects your plugin works fine, thank you very much!
