Capture setting

Hi, I had to use the highest setting to fix the insecure items on my SSL website. Most of the items were images but there were two that had to do with the theme I’m using. I’m worried about keeping this plugin active since it says the Capture setting has the most impact on memory usage and biggest potential to break things.

Any ideas on what I should do to prevent any problems?

Also, even though everything is fixed per the Why No Padlock test, I still don’t get a padlock.

My website is http://www.thecolibriproject.com

Any help is appreciated!
