That fork dropout almost looks squished in the pic. Try putting the endcap into the top of the dropout with the wheel outside the fork, does it go in?
Check the rear dropout from front to back also.
I had a pinarello whose rear dropout had gotten pinched in a bit. I just put a pipe over the dropout/hanger and gently coaxed it open a bit.
