Hello,
I have been arising with a mixed content issue in contact form 7 on WordPress when I have added an SSL certificate to my website.
Please make sure your website is fully configured to use HTTPS URLs. If your website supports HTTPS, it should use HTTPS, and you shouldn’t want to do send some data through HTTP anyways (no matter how easy a plugin makes it).
If you use a service like Cloudflare’s HTTPS rewrites, please disable it and set your WordPress Website URL correctly instead. Magical fixes are great if they work, and a confusing mess when they don’t, so I would try to avoid them.
