How Fix Calculated Fields Form (CFF) Plugin from redirecting AMP pages to HTTPS

1 minute, 18 seconds Read

If you have an AMP WordPress website and Calculated Fields Form (CFF) plugin, you may be aware that your forms actually don’t load on the AMP pages this is a cause for concern with user’s experience resulting in them leaving.

I was first made aware of this issue in Google Search Console formerly known as Google Webmasters after seeing URL not found (404) errors for AMP.

After viewing a few of my posts that contained forms I noticed it was caused by the Calculated Field Forms plugin itself. The plugin would try to redirect AMP pages to a HTTPS link. And since I do not have SSL enabled on this website as there is no reason to, this is not good for users visiting posts that have forms.

After trying to search for fixes I stumbled across a very unhelpful post by the plugin developer themselves. Not satisfied with this I set out to fix the issue myself.

All it took was a simple small edit of the from the Plugin Editor.

How to fix

From your WordPress Dashboard navigate to Plugins > Plugin Editor

From the Plugin Editor page select Calculated Fields Form from the drop down list of plugins to edit.

Open up the file from the Plugin Files sidebar.

wp_redirect( “https://$host$request_uri” );

Change to:
wp_redirect( “http://$host$request_uri” );

Once you have made the change click Update File to save the changes.

NOTE: You will need to do this again every time you update the plugin.
