Chester are likely to cease to exist in the next few days (as already noted elsewhere), but Palace and Cardiff seem to have financial troubles.
Palace are 10 days late paying wages :
Crystal Palace’s financial crisis has deepened after manager Neil Warnock and his players were asked to take a 10-day pay delay.
The club’s football staff and management were called into an emergency meeting after Saturday’s 3-0 home win over Watford to be told their wages would not be paid tomorrow....

And also persistent stories rumbling around that Cardiff won't be able to last the season out - almost certain that if they don't go up this year they'll go into administration, but there's a fair chance they won't last that long to find out. (apologies, no links I can give on this one.) Ridsdale does have "form" on this, of course.
