It looks like you are currently working on the options with Jason in a ticket. As for the error you are getting when you confirm the order the message is saying that the output started in the WA_eCart_Database_PHP.php on line 199. My file has only 100 lines in it total. Do you have a file with this name that has more lines then this? You should try making a backup of this file and overwriting it with the default version from the download. If you continue to have this problem please post back with this Database file so we can take a look.
