Redirected to existing page

hi Vasyl,
I have been having a problem with the plugin.
The situation is this:
When a visitor tries to access a specific page on the site that is locked for him (restrict access to read), he is redirected to an existing page. When I as an admin, try to reach the same destination, the plugin redirects me to an existing page as well, failing to identify me as an admin.
Any suggestions?
