Error in Event Ticketing Screen

The following error shows on the top of the page on an event with ticketing setup. All other events show correctly without error.

Warning: http_build_query(): Parameter 1 expected to be Array or Object. Incorrect value given in /home/thendara/public_html/wp-includes/Requests/Transport/cURL.php on line 507

I set ticket to free and it seems to work ok, just this error on screen.

Time.ly Paid Version 2.5.10
