Recently I have activated SSL and my site has problems of operation when I visit it with a secure connection (HTTPS).
Since the secure connection does not interest me, how can I automatically transfer all HTTPS requests to HTTP?
First of all, please note that if your SSL configuration is not correct (i.e. you see SSL errors), it’s not possible to redirect people away from the SSL error. That’s simply a fact of how HTTPS works.
If it’s just about mixed content warnings or something like that, you can force people away from HTTPS in the same way you can force them onto HTTPS. We have a guide about that as well. Simply replace https with http in that article (and in reverse) and you’re good to go.
