Bug in filter-hook for “page_link”

Hey!

I found an issue that causes the URL-field to disappear when editing a page, meaning that you can’t change the permalink/slug.

How to replicate:

1. Set up a plain WP installation
2. Go to a page and see that you can change the permalink in the “Page”-section in the sidebar by changing the field “URL”.
3. Install this plugin and activate it.
4. Go back to the page and see that the URL-field has disappeared.

I also found the fix. In the file “inc/init.php”, line number 59-60 should be replaced with:

if(is_admin()) return $link;

The current code causes the filter “page_link” to return null when in WP Admin-context. If this is intentionally then you find a different way to solve what you’re trying to achieve as this interferes with WP.

Best regards
