PE2, PE3 and PE4 are directly connected to the expansion port.

Hardware: Do to mechanical stress, the vias may be broken. Try to
measure the result directly at the CPU pins.

Software: You enabled any special peripheral on these pins? You used the
right I/O call with the right bit/mask?
sbi(PORTE, PE4),
but outr(inr(PORTE), _BV(PE4));

Try something simple like
