Hi, I have exactly the same problem. I installed the Free Edition of BookIt yesterday and it worked fine at the beginning. But while testing, means adding and deleting objects, I received the same error message as Lyle described. I also deleted the tables in the database and reinstalled the application. I contacted my provider to set the memory_limit to 64M. It's not working anymore. Can someone help? Lucie.

Booking Paid. I will upgrade if necessary I have several filks who needd this. If, I can get it working.

I was able to eliminate the memory error. I change memory limit in php.ini file and removed the sample data and created a new object.

I am still getting error in my objects"Warning: Invalid argument supplied for foreach() in /home/content/22/7581622/html/libraries/joomla/database/database/mysql.php on line 701" and I cant select check in oer check out.
Thanks

Version 1.22 I tried upgrading from you server and got this error code: "Fatal error: Call to a member function enqueueMessage() on a non-object in /home/content/22/7581622/html/administrator/components/com_booking/models/upgrade.php on line 165" And the monthly calendar on frontend getsd:500 - DateTime::__construct() [datetime.--construct]: Failed to parse time string (2011-04-03 33:00) at position 11 (3): Unexpected character

New version seems to have fixed my error codes. Thanks Guys
