Try to request an SSL certificate from the Client Area and install it on the “SSL/TLS” section of the Control Panel for your domain by following this article from “Installing an existing certificate” to stop this from happening, or change the WordPress URL from HTTPS to HTTP by following this guide:
- Go to your Control Panel, then click on “MySQL Databases”.
- Click on “Admin” near the database you want to go to phpMyAdmin.
- Search for a table named
wp_options (it may also vary depending on the WordPress installation), and click on it.
- Edit the
home values to have the HTTP version of your domain (for example,
https://yourdomain will become
http://yourdomain) and execute the query.
