you’ll need to open the file a client
I tried to parse this a few times, without success, so let me see if I can guess the actions I need to take.
I need to open the data.db file in the <project root>/.tmp folder using DBeaver and remove the strapi_administrators table.
So, I installed DBeaver community edition - it seems a lot more complicated than say Microsoft’s SQL. This is a perception based on a few minutes long attempts to open this <project root>/.tmp/data.db. It seems that unless I am running it as administrator, nothing ever happens. If this is true that darn manual should say it before anything else.
So trying to save my back-end (Strapi) application database I tried to just recreate the admin user - and got stuck into mucking with DBeaver
