Hello,
are you using the plugin on a regular site or a Multisite? The plugin always uses the home URL domain. I’m not sure if I can help you unless I have more detailed information on your setup.
It is a regular site.
It shows a cert registered for the server domain bigtrousers.com.au
Not the website domain where the plugin is installed mxcproject.com.au
What value do you have in the “Home URL” setting for your site?
I’m not sure if it’s possible for me to help you with this remotely. I cannot recreate the issue, and I could not yet find anything in the code possibly causing this. The plugin relies on the Home URL to detect for which domain to create the certificate. Where exactly does it show the wrong URL?
