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)
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 "https"
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.
