I'm also experiencing this, but with the following database name: "glasgow-locum-group_production" (minus quotes). I'm using mariaDB 5.5.32.

I'm going to have a dig and see if I can cook up a pull request.

@johnhamelink - I forgot to say: thank you for taking care of this! 👍

No problem @sevein!

Could it be that this error is back again?
