after solving this Virtual hosts Options with @mrmarkuz, I am facing now another problem with SSL certificate for my site.
I have downloaded ssl certificate from Let’s Encrypt.
I have setup this cert as default cert.
In virtualhost config i have checked
Require SSL encrypted connection.
On PrestaShop configuration i have turned on SSL and another option which is Enable SSL on all pages.
after that main site page is not working shouting about redirection problems, but the admin page (backoffice) is working ok - with ssl certificate.
Does anyone of you faced maybe the same problems ?
I think that it would be “nice” if i.e. we can install/request multiple SSL certs for different virtualhost and in that config choose proper SSL cert for them from the NethGUI.
