I have cleared the browser and re booted over a 3 day period but still get the same error. Is this problem my end or your end.

Basically Type 1 is where eliminations are made off the chain - ie there is a clear set of candidates with alternating colours but no contradition. Two cells with different colours point to a third candidate off the chain which can be removed since one of those two colours must be a solution
Type 2 occurs on the chain. That is where two of the same colour appear in the same unit. All of those of that colour must be wrong.
Hope that helps a bit
