updateByte gives error "Exceeded maximum number of writes"

[webnology-ch]

When setting: const int maxAllowedWrites = 1; and using the updateByte function I get the error: "Exceeded maximum number of writes".

this does NOT happen if: const int maxAllowedWrites = 2;

if I use writeByte and const int maxAllowedWrites = 1; the error does not appear.
