If you encounter the error “An error occurred on the server when processing the URL. Please contact the system administrator.” when attempting to view a page on your site, and your site is otherwise functioning correclty, the issue is caused by a “Gated” page.
“Gated” lead forms are lead forms that are displayed to your visitors before they can view another web page. You may experience an issue which causes the gated lead form to display an error instead of the form or web page.
To resolve this issue, delete and recreate the gated lead form, or remove it from the web page altogether.
