Thanks @MJ, Thanks @PitaJ
both hints helped. My nodebb did not load pages like themes/skins properly, so I tried to get websockets to work. I bypassed my shared hoster env by using an self compiled nginx on a non-privileged port and ssh tunnel (to prevent firefall changes) on that system, and that way I got websockets. Now I was able to load the theme page and so I switched to another theme, restarted and switched back to my current theme. Afterwards I stopped my temporary nginx-ws-tunnel-solution and the mobile page works for me now.
Next step: Find a solution for a permanently working websocket setup on my hosters systems.
Hm... thanks @jtarjanyi. Can you let us know what git hash you are using now?
Currently using the manualy downloaded version from here: https://github.com/designcreateplay/NodeBB/archive/v0.3.1.tar.gz
Thanks i will check it.
Took me about an hour but I think I found the source of the issue:
What's happening is that if a relative path is detected in a markdown url, this code checks that the relative path prefix is there. I'm not really sure why this is the case. If I'm running Wordpres (I am) and upload images there, shouldn't I be able to use relative URLs without enforcing the relative_path?
(For my reference, the relative path is set based on the site url)
As replied here https://community.nodebb.org/topic/2217/how-can-i-display-3-columns-in-the-lavender-homepage/2
Just change col-md-4 by col-md-2 And on the first category you need to add col-md-offset-1 aswell.
This method will only work with second solution. Or you can add col-md-2 col-md-offset-1 aswell on the first item in ACP after doing first solution.
