Thanks for the reply.
Permssions error of doom on mkdir... as per previous type errors. It kind of doesn't matter for this install as it's only being used to test the importability of a discourse database.
Yes I run ./nodebb build after any installs via cmd line.
However I stepped away for a couple of hours from this, read you reply then logged in to ACP and BOOM I can see the IMPORT in plugins menu and ancillary screens!
Good tip /admin/plugins/import by the way! Kind of handy for future reference.
I appreciate your patience, questions and insight always 👍
