Problem w/ generator hook up to breaker box SEE PHOTOS

I have a question I installed a double 30 amp
breaker w/ interlock on my panel, ran the 10/3 w Ground to a box w/ male end.
Today I hooked up my generator 7500 watt to the male plug via a extension cord
10/3 w/ ground which came w/ the generator. PROBLEM: Only the right side half of breaker box is getting power . I double checked all the wiring from the breaker box
to the outlet , and outlet to the 30 amp female plug on the generator, all appears well.
What could be the problem ? Thanks in advance.Name:  DSC03390.jpg

If you were missing a hot leg every other breaker top to bottom would not work, not one side or the other.

Start at the panel where the feeder originates (the panel in the picture). Measure voltage between the two hots (240v) and from hot to neutral/ground(120v).

Next measure where the feeder ends, at your transfer panel I assume. You should get the same readings. Keep going down the line until you lose your voltage and you will find your issue.
