I use WooCommerce on my WordPress site and I have just forced HTTPS redirect for the Checkout flow. However, when I do this, my custom CSS is blocked. I get:
Mixed Content: The page at
https://www.example.co.uk/blog/product/myProduct/was loaded over HTTPS, but requested an insecure stylesheet
http://www.example.co.uk/blog/?sccss=1&ver=fe62ddea3ed1898e6866564ccdc86c01. This request has been blocked; the content must be served over HTTPS.
My custom CSS is produced by the simple custom CSS plugin.
How can I fix this / work around it?
