Cardiff remain top of League One despite having to come from behind to draw 1-1 at Leyton Orient.
A first-half equaliser from Yousef Salech cancelled out an opener from Dom Ballard in a game of few other chances.
The visitors, who were hit by a transfer embargo due to non-submission of annual accounts, went behind after 12 minutes to an awful blunder from goalkeeper Nathan Trott.
The shotstopper took too long on the ball after playing a one-two with Gabriel Osho and allowed Ballard to rob him and easily slot home.
Trott redeemed himself on 21 minutes when he palmed away a header from the onrushing Alfie Lloyd at close range.
Cardiff equalised on 33 minutes with a superb solo 50-yard run by Salech, where his power and pace was too much for the home backline – before rounding Killian Cahill to slot home.
The closest either side got to a winner was when Tom James pulled off a superb 74th-minute block to deny Alex Robertson, after being laid on by Salech.
