@pitaj You are right, git checkout version and nodejs downgrade did the trick.
Thanks a lot!
Trying to upgrade as stated in the topic, receiving this error:
Error: Cannot find module 'ip'
npm install ip then upgrade again
Did that successfully. Upgrade seemed to go ok, then received these errors trying to start nodebb, it's like the upgrade script didn't work: ( Can I reinstall the latest version of nodebb, and have it keep my setup, users, posts etc., or does a clean install initialize Mongodb?)
"./nodebb stop" to stop the NodeBB server
