2 errors

I am running into two errors. The site is in development: http://long2consulting.com/sewcreativefairport/index.php/calendar/

1. The first error is when I click the next or previous month or try to change the view to agenda etc. I get the following:
Something went wrong while fetching events.
The request status is: 200
The error thrown was: SyntaxError: expected expression, got ‘<‘
Click here for technical details (just shows the source code for the site)

2. The second error occurs when entering events. When I click New Event the following warning appears. I am still able to make an event, but would like to know how to fix this so this warning does not appear.
Warning: http_build_query(): Parameter 1 expected to be Array or Object. Incorrect value given in …/public_html/sewcreativefairport/wp-includes/Requests/Transport/cURL.php on line 508

Please note I truncated the beginning of the path so my home directory name is not shown here.
