Most likely, the page has “escaped” Ghostlab’s control. You can verify this by checking the URL in the browser bar. If it’s the regular URL instead of Ghostlab’s server URL (something like http://22.214.171.124:8005/…), the “escape” happened.
By default, the level is set to 1, which doesn’t do any active rewriting, since the rewriting can have an impact on the site performance. Increase the level by one step and try if the problem is solved. If not, go one level higher, etc.
If this still doesn’t help, please get in touch with the technical support and provide a publicly accessible URL on which the problem occurs and a description when the problem occurs so we can reproduce the issue.
