My theme is not using https. No padlock

hello folks, being a complete newb and new to this fine world I am having an issue with my ssl cert not giving me the padlock. It seems that all is well except my actual theme (using Sprite) I am sure someone maybe able to help me. I have searched to see if this has come up in discussions in the past but couldn't locate. lol I must be an extreme case of newb :slight_smile: thank you all in advance
