I am having the same issue, but you appear to be having some other issues as well. I had the same ones and have been going through and ensuring I have everything right.
The first issue I see, is that your [email protected] account is not present. If you did not delete it, this indicates a database connection error. I fixed mine, but now I am still having a problem. I also cannot login using the default [email protected]
I then tried your fix, but I still cannot add new accounts.
