My domain is: www.nezrougezuerich.ch
My operating system is: Linux h2web13 3.14.59-imu
My web server is: Apache 2.2.x
My hosting provider, if applicable, is: infomaniak
I can login to a root shell on my machine: I don’t know
I’m using a control panel to manage my site : yes
I installed the Let’s encrypt SSL certificate on the site mentioned above. Unfortunately I had to delete it again since some parts of the site are on an external server and there is no possibility to install the certificate there. Browsers will therefore block some content loaded from this external server. This is why I went back to non-ssl via the infomaniak control panel. After this I get the SEC_ERROR_UNKNOWN_ISSUER errormessage.
I do not understand why there is a problem since I think I uninstalled the certificate completely and should therefore have the site back to http instead of https.
Strange thing is, when I restore to a backup from before installing the SSL certificate the first time the problem is not resolved.
I also tried redirecting the site via .htaccess. Hence I guess I might not have used the right rules.
Many thanks in advance for reading this. I hope you can give me hints on what to try.
Please let me know if you need additional information.
