WordPress resources refusing to use HTTPS

Hi,

Have a problem involving HTTPS that I hope the community can help with!

I’ve set up a WordPress installation for one of our clients, and our hosting provider has installed our SSL certificate (which I’m 100%sure is working fine). I’ve gone through the usual process of changing the URLs in the general settings to https, using a find and replace plugin (Go Live) to change everything in the database over to HTTPS, and have used code in the HTACCESS file to force HTTPS. However, for some reason the website resources (CSS and Javascript) are not loading over the correct protocol, which is obviously breaking the website.

I’ve double checked the database and I’m pretty sure the Go Live plugin did it’s job, and as advised by our hosting provider I used an external tool (https://interconnectit.com/products/search-and-replace-for-wordpress-databases/) to make changed to the database, which only ended up changing some cached WordFence traffic views.

Feeling a bit stuck and would really appreciate any input.

Thanks,
Anthony
