Hello Rogier,
Yes i checked, I’m using 6.1.0 version of Really Simple SSL.
I downloaded the certificate with really simple ssl 90 days ago and it was working fine. After 90 days, the certificate expired and I had to renew it. Unfortunately, the Settings page is currently showing as a blank page. When I enter my domain to use The Let’s Encrypt Wizard via https://really-simple-ssl.com/install-ssl-certificate/, it still throws me at the same blank page (page is not loading) . So I can’t get a certificate again.
If you want, you can see the blank page i’m talking about here. https://www.canva.com/design/DAFXcn4EqyY/ZaX4HUkBbqDm6wiIpy5Nyg/view?utm_content=DAFXcn4EqyY&utm_campaign=designshare&utm_medium=link&utm_source=publishsharelink
