@bentael Thanks for getting back to me and for all your help. In the end, Nifty took over my access to DigitalOcean and managed to set up Nodebb with my Mybb import.
It didn't work out the way he wanted, he had to dump on my droplet, the install he had worked out on his own computer with the import already included.
His guess was that my droplet was fighting the import since I had chosen the 512mo ram plan.
