me too! I've had other critical errors on PlanetMath since 2013 which made me think to myself, I would love to contact whomever is necessary for myself to contribute fixes.

I guess today is the day I am now serious about joining the Development effort.

My own error message is nearly identical, and occurs on most pages when I am logged in:
