I managed to fix it by disabling the plugin, which let me then edit the post and I've also replaced the plugin with one that's actually maintained.
Thanks again for the help in locating this error.
Hi, I expected to see new mobile theme after updating NodeBB to version 1.7.0 . But you can see old theme below. Are there anything that need to be activated?
What new mobile theme?
I don't know, I've been updating NodeBB with these commands:
git pull origin master
And everything would be get done automaticly, should I do anything for the new theme?
There isn't a new mobile theme. If you're referring to the new slideout menus, they are still in testing.
