# Customizer Problem (Not Found)

 * Hello,
 * I am trying to integrate HappyForms into my current web project for a customer.
   I like the style of the plugin very much and I consider buying a full licence
   later. But for now I cannot make it work, because of some weired URL-building
   problem. My site is hosted under [https://dev.madwizard.de/dorfplatzl](https://dev.madwizard.de/dorfplatzl),
   behind a reverse proxy (Traefik). Everything is working fine and the default 
   wordpress customizer is loading correctly. But when I try to edit a happy form
   I get the following problem:
 *     ```
       Not Found
       The requested URL was not found on this server.
   
       Apache/2.4.29 (Ubuntu) Server at dev.madwizard.de Port 80
       ```
   
 * I the web developer I see its because of a HTTP 404 trying to access:
    [https://dev.madwizard.de/dorfplatzl?post_type=happyform&p=286&preview=true&customize_changeset_uuid=da5e3bf9-03ba-4cab-a92e-25c9aa8cc6e8&customize_theme=default&customize_messenger_channel=preview-0](https://dev.madwizard.de/dorfplatzl?post_type=happyform&p=286&preview=true&customize_changeset_uuid=da5e3bf9-03ba-4cab-a92e-25c9aa8cc6e8&customize_theme=default&customize_messenger_channel=preview-0)
 * While building the URL, it seems the plugin fails to add a trailing “/” after
   the context root (dorfplatzl). When I add it manually in a new window, the page
   loads nice and clean. But with this I lose the integrated editing experience.
 * I am using wordpress 5.5.0 in a dockerized environment. I tried to add the trailing
   slash in the settings page, but wordpress canonicalizes the URL afterwards to
   the form without trailing slash.
 * Do you have an idea, why this is happening and how to amend this error?

 * Hey there! 👋
 * That looks really weird — the URL you shared is also missing 2 parameters required
   for HappyForms Edit Form screen to kick in. Would you write us an email at support(
   at)thethemefoundry(dot)com, so we can troubleshoot a bit faster? When we’ve finally
   found the cause and its solution, we’ll make sure to update this forum thread.
 * Let us know!
