Just to clarify, a blocker is not a higher priority level than a major. A blocker is a special status for an issue that is preventing other issues from being addressed. A issue set to major means it is adversely affecting users and needs to be fixed as soon as possible.

I will go ahead and do the temporary fix for this, but this issue needs to be addressed in a more permanent manner as suggested in Issue #32

Turns out this issue cropped up because the database settings weren't updated despite the recent change
