No, it is not a hacking attempt but a db error. That comes from a custom mod I think, try to ask at its own thread about this.

It appears as though you recently installed an incompatible PayPal Donations modification.
Without knowing anything beyond the clues in the posted error, I would suggest you first disable your PayPal donations modification via the AdminCP Plugins &Products Menu and see if perhaps the mod has been updated, quarantined, replaced, or such.
