@Scuzz. For the moment for it to work on 0.7 on my install I have removed the hooks for usersettings, but if I have any time soon I will try to make those work also. This at the moment was shown that maybe someone will make use of the code before I will make it stable.
Katex plugin problem
Plugin I am using : nodebb-plugin-katex
Oops! Looks like something went wrong!
Failed to lookup view "admin/plugins/katex" in views directory "/home/sub-dir/public_html/subdire/NodeBB/build/public/templates"
Did you rebuild assets after installing it? There is a "rebuild and restart" button in ACP.
Thanks a lot , it worked !!
