getting codes from my db is not working. Any advice?

[CODE-NINJA]

You have again the same mistake.
You settep-up your database-ID the wrong way.

1. Is it → Diamonds
2. or diamonds
3. or Diamond
4. or diamond
5. or DIAMONDS
6. or DIAMOND

Please take care on this. It is CASE-sensitive!

This is why your DB does not exists in the error-log.
