Page Manager Error: The requested page "/xxxx" could not be found I am working almost 4 hours on the following problem, and can't solve it (Drupal 7).

I tried to build a new simple page in the page manager as I did few times before.
I entered a simple path as /xxxx
Then, after I saved the page, and tried to load it, I got the following error message:


  The requested page "/xxxx" could not be found


Can somebody help me figure out why I can't create new page?

In addition, when I tried to disabled the page on the page manager, I got the following error:


  Notice: Undefined offset: 1 in
  template_preprocess_page_manager_edit_page() (line 42 of
  D:\MYSITE\sites\all\modules\ctools\page_manager\theme\page_manager.theme.inc


Does someone knows what is the problem, and how can I fix it?

Thanks!
Are you using the stable version of the ctools and panels module, this error doesn't seems to be in the issue queue of the respective modules.

As @David as mentioned the problem could be of selection rule or the access rule.

Have a look at the use tutorial for creating the page with page manager: http://nodeone.se/en/learn-page-manager-part-1-overview

Also check the documentation of the page manager module: https://drupal.org/node/1862908
