[wp-testers] WordPress 3.0: problem with empty excerpts beingreturned by the_excerpt()

[Administrator]

Just a thought...it sounds like the except display function is detecting 
some remnant of the excerpt or more likely that when a variable was set for 
excerpt display that the variable doesn't get reset when you delete the 
excerpt.

May I suggest to lock down where that is for the code junkies that you 
create a new post, create an except and save to draft.  Edit and remove the 
excerpt then publish.  If a blank excerpt box comes up then the variable 
must not be getting reset in the posting functions.  Darren just sent you 
some code that may "fix" the problem"  Looks like the code says if the 
string length of the excerpt is 55 or less then don't display.  Anyway, 
hoped this helped.
