thank you so much brother
I've forked nodebb-theme-quickstart to begin to make my first persona's child theme, everything look work fine except this warning when it load the theme:
2018-11-12T21:42:41.690Z  - warn: [plugins/load] The following plugins may not be compatible with your version of NodeBB. This may cause unintended behaviour or crashing. In the event of an unresponsive NodeBB caused by this plugin, run
./nodebb reset -p PLUGINNAME to disable it.
I'm missing something ?
I've also another problem, if I install a new plugin my child theme is deleted
You need to add your child theme under dependencies in package.json
I've solved "nbbpm" compatibility tag need to be in theme package.json, pheraps should be a good idea add it to the quickstart theme on github
