How to debug "Future home of something quite cool" issue?
There can be multiple reasons for this. Below are a few of them listed which you can follow to debug the cause :
1. Th website has an expired certificate -
When your site's SSL certificate expires it starts showing "Not Secure" in the address bar. In order to install a new certificate, it is always better to delete the expired one first.
Depending on your hosting provider, you can delete the expired certificate. You might see the below screen after uninstalling the certificate :
The reason you might be seeing the above error is that, even if the expired certificate was deleted, the site is still pointing to HTTPS instead of HTTP. The site can be redirected to HTTPS only when it has a certificate. Since the certificate has been deleted it is always recommended to point the site back to HTTP.
2. Rename the plugins folder in WordPress -
If even after following the above method the issue is not resolved, the issue can be caused due to the theme or any of the plugins. So rename the plugins folder of your WordPress installation at the following path -> wp-content/plugins. For example, you can rename it to something like "plugins_new".Once you have renamed it, try accessing your site. If the issue is resolved make sure you rename the plugins folder to the original name "plugins". Also do not forget to activate the plugins that you want to keep active since renaming the plugins folder deactivates all the plugins.
