What should I do if my API Key is already registered on another domain / website?

If you have tried to enter a new API key for one of your domains and you get the error message "Domain Already Registered With Another API Key ..." then there are a number of possible reasons for that.

MPP Hosting

The most common one is that you are on MPP hosting and have installed your site as a sub domain of MPP hosting.

If your domain looks like https://mydomain-com.magicpagehost.com then you need to go back into your Cpanel and then click the re-install WordPress button.

When the pop up appears pick your domain and re-install WordPress. Once you have installed Magic Page Plugin again then you should be able to apply your new API key.

Before you install WordPress on another one of your sites I would check out the video HERE on adding WordPress to MPP hosting

Staging Domains On Other Hosts

The same can also apply if you try to use a staging domain on one of the other hosting companies. If that is the case then you need to add MPP to a domain name and not as a staging site

Changed API Keys

If none of the above are true then your site must have been registered with another API key. To fix that simply click on the blue link and enter in the required data in the fields provided. Domain Name (Without https://), Original API Key, New API Key. If you have the old API key on a number of domains then you can change them all at once by checking the "Apply this change to all my domains using this api key" box.
