Answer
Yes. No.
Work Step by Step
The electric field is zero exactly midway between the two equal positive charges. The electric fields due to each charge are of equal magnitude and opposite direction, and they sum to zero there.
However, the electric potential is never zero along that line, except at infinity. The electric potential due to each charge is positive, and V is a scalar quantity so the total potential is always positive (except at an infinite distance from the two charges).
