I know this is not a wp-related question, so forgive me for the low starting value on this solution as I am unsure if it allowed to be posted.
I have recently gained an SSL certificate for my domain sound-affair.com. It is set up and working and I have made amendments to the correct config.php files.
I have visited this site (http://www.whynopadlock.com/ ) and it has defined all of the SSL insecurities, these are mainly simple things such as images. However my site does not get the green padlock secure symbol in the browser. instead I get the error "This Page has insecure content" Dont Load (recommend) or Load anyway buttons when i enter the checkout. This obviously doesn't look great for customers.
Using http://www.whynopadlock.com/ and entering the domain https://www.sound-affair.com shows all of the highlited issues with the site.
After a bit of googling I have seen some solutions regarding images cant be an absolute paths, but there also appears to be some plugin in-securities.
I know someone with the correct experience in opencart and SSL can probably knock this problem out quite quickly.
If someone has the ability to login and resolve these issues I will happily pay $25.
