[pmwiki-users] error never seen before

[Stephen Schwerdfeger]

been using pmwiki for about 6 months....have never seen this before...

all of a sudden, this week....started getting this error trying to  
access various pages...not consistent...sometimes to edit, sometimes  
to view...can't find pattern yet....

any suggestions?????????

---------
The server encountered an unexpected condition which prevented it  
from fulfilling the request.
The script had an error or it did not produce any output. If there  
was an error, you should be able to see it in the error log.
