Upfront - Spirit - errors with https


I'm getting the following errors when loading https (I've changed the url to "website.com when referenced below for the sake of privacy):
Mixed Content: The page at 'https://website.com/' was loaded over HTTPS, but requested an insecure image 'http://website.com/wp-content/themes/uf-spirit/images/sprite.svg'. This content should also be served over HTTPS.
jquery.js:4 The specified value "!" does not conform to the required format. The format is "#rrggbb" where rr, gg, bb are two-digit hexadecimal numbers.
https://website.com/wp-content/themes/uf-spirit/images/sprite.svg Failed to load resource: the server responded with a status of 404 (Not Found)
maps.google.com/maps-api-v3/api/js/23/7/util.js:23 Google Maps API warning: SensorNotRequired https://developers.google.com/maps/documentation/javascript/error-messages#sensor-not-required

How do I fix these errors?
