My domains are www.ekumen.net and www.ekumen.eu. Everything works on all browsers on my home desktop.
But on my laptop running on windows 7, only firefox is working well.
On google chrome, when I use one of these urls, I obtain this message : NET::ERR_CERT_AUTHORITY_INVALID
Same problem with Opera and IE.
I tried quite everything : empty the cache, stop the avast antivirus, reinstall chrome… Nothing changes.
This problem only appears on my laptop : I haven’t seen this problem on any browser on the other PCs.
What do you think I should do ?
