I'm using

I'm using the Spirit theme and trying to install a SSL certificate through my hosting company. I have a number of insecure URLs when checking via http://www.whynopadlock.com. These are all js and css to do with the spirit theme. Some of these are to do with the Google search plugin which hopefully will go away if I delete that as I probably will not use.

Is this something that can be resolved easily or shall I look to use another theme?
