fix prestashop 1.3.7 SSL warning on chrome browser

hi dear, here is peter,and i want to ask someone who can fix my prestashop SSL warning on Chrome browser,here is my site: [login to view URL] and when i type "https://" it shows SSL warning on chrome browser. i have ask the host to figure out what's wrong with that. because there are some links are with "http://" expecially for the images,and some other [login to view URL] said need to change them all to "https://",but as everyone knows,if change all of them ,that's not good for google crawler,and will effect the SEO ,and cause my site is online shop,so it's very important for the SEO. if anyone who knows how to fix [login to view URL] contact me any time.thanks.
