I installed a stock version of pre11, and I now get this again:

Warning: Missing argument 1 for ec3_filter_query_vars_vcal() in /home/ 
wscamra/wp-content/plugins/eventcalendar3/eventcalendar3.php on line 336

Warning: Cannot modify header information - headers already sent by  
(output started at /home/wscamra/wp-content/plugins/eventcalendar3/ 
eventcalendar3.php:336) in /home/wscamra/wp-content/plugins/ 
eventcalendar3/eventcalendar3.php on line 345

about 6 lines before the VCAL output appears (not sure if this is  
valid or not - it looks OK):

So, the same sort of problem that Holly's having, albeit without the  
SQL errors.

I can remove the errors either by setting defaults, as I mentioned in  
my previous message, or by prefixing the call to  
ec3_filter_query_vars_vcal() with an @ sign so PHP suppresses the  
warning, but this produces a seemingly valid calendar file that  
causes iCal to hide all appointments in all calendars when subscribed  
to. At least it didn't crash this time :)

My ISP, ever up-to-date, is running PHP 4.3.10 and MySQL 4.0.24, if  
that helps.

(and sorry, Darrell, if you get this twice - Mail helpfully defaulted  
to sending it from an address that wasn't authorised to post to the  
list :)

Thanks
