Sorry to hear that, it sounds like you will need to restore your forum from backup
I had nodebb in version v0.6.0 so I did upgrade to v0.7.0 but I get a message about a bad database schema. So I did the update to v0.6.1 and then to v0.7.0. After starting, message appeared about incompatible plugins. I did
node app.js --reset --plugins but still I received an error:
4/6 13:03  - warn: [plugins / nodebb-theme-lavender] This small plugin not be compatible with your version of NodeBB. This small cause unintended behavior or crashing. 4/6 13:03  - warn: [plugins / nodebb-theme-lavender] In the event of an unresponsive NodeBB Caused by this plugin, run ./nodebb reset plugin = "nodebb-theme-lavender".
./nodebb reset plugin="nodebb-theme-lavender" too and nothing.
How can i fix this problem?
@Mifczu That's not a problem, just a warning. Don't worry about it, lavender is compatible with NodeBB v0.7.0
