But in config.json i have http://...... Edit it to https:// solved the problem.
Before version 1.11.0 i don't have this problem.
Thanks, that solved the problem for me as well, changing http to https. And as for you, I did not have this problem before 1.11.0
But then an other problem turned up: "Invalid CSRF Token"
Pls see this link https://community.nodebb.org/topic/9222/invalid-csrf-token
My solution for this was what is written in the end (I use Apache2)
RequestHeader set X-Forwarded-Proto "https"
for the record for people finding this via search, for apache2 you have to set this somewhere in your nodebb vhost configuration
RequestHeader set X-Forwarded-Proto "http"
you might have to enable mod_headers to do so!
So upgrading to 1.11.0 gave me a problem that had to be solved in 2 steps. First by changing in config.json, then I had to modify Apache2 settings.
