I am new to WordPress. I have a site and created my first sibling page. I am using permalinks. All the other pages go to the proper display. However from the parent page, when I click on the link for the sibling page, the permalink is correct, but I get the page not found error. What is odd is when I am on the page not found link, if I copy the URL from the address bar and paste it back in as is and hit enter, the page will display okay. The page also displays ok if I select View Page while in the admin panel. Only seems to be a problem when I use the link from the parent page?
I did check my .htaccess file is correct. I tried setting the permalink to default, and then back to the Post Name setting.
Is there anything special that is required in a template page for a sibling page? What else should I look at?
