Sorry, I haven't kept the game details to show this graphically.

In a game of blitz recently, I put my opponent in check with a double pawn move. He could've taken the pawn en passant but the game ended there as checkmate. Is this correct or is it a glitch on the blitz site?

glitch or wrong interpretation of the en passant rule.

This is a long shot, but was the pawn that could have taken the other pawn en passant, pinned to the king by any chance?

There is a bug in blitz (has been discussed in previous threads).
You cannot e.p. out of check in blitz

No, the only other pieces involved were two knights and another pawn. Sorry, I really should have taken a screen shot
