Custom Permalink Conflict with Cornerstone

[Formula_Design]

I am trying to use redefine my permalinks to “Post Name” remove /index.php/… from the order in my page URLs. However, when I do this in the permalink settings both my published pages and Cornerstone are inaccessible and I receive the following error message on the page that loads…

"Not Found
The requested URL /x/ was not found on this server.

Apache/2.4.7 (Ubuntu) Server at formula.design Port 80"

What is the cause and how may I fix the issue.

Thanks.

Hello There,

Thanks for writing in!

Go to your WP-ADMIN --> Settings --> Permalink and use the permalink structure change there, if it generate any .htaccess file copy the content and update your .htaccess file.

Or Check if your hosting mod_rewrite is enable by creating a file phpinfo.php with content,

<?php phpinfo();?>

Upload this file and browse via Browser. So you know which modules are enabled. You need mod_rewrite enable to remove index.php from URL.

Hope this helps.
