OK - from the jpg we know that admin's user_id is 53 so we can now look at whether he is in fact active, so lets use mysql again and use the query:

select name,active+10 entities where entity_id = 53;

This will show something like (in my system admin is user_id 154)

The active value is in fact a single bit which is 0 or 1 (boolean false or true), and the "active+10" forces mysql to convert it to a number so it is printable - so the 11 means that the value is 1 - ie true.

[By the way - I assue that the password for admin that you blurred in your jpg is quite readable and makes sense to you - ie it is set to admin1234 or freddy42 or something that seems familiar - ie it is real characters that you can type.]

It the above shows that 'active+10' is actually 10 on your system then somehow the user admin has been deactivated.

We can set it back to active using the sql:

update entities set active=1 where entity_id=53;

Note that I checked on my system that de-activating the admin user gives you the same error as though you had typed in the wrong password - ie
