I changed certificate in IIS 7, changed bindings on websites, everything OK. But when I'm trying to set my old certificate (and I'm changed bindings too), I still get new certificate instead of old. I deleted cache, certificates from browser, opened from another machines, but there is no effect. When I open website from machine, where is it runned, I can see, that there is my old certificate, so IIS7 changed certificate... But where the certificate can be cached? P.S. To prevent misunderstanding - I want to return to my OLD certificate.
Try downloading ssltools manager to verify that certificate was indeed deleted. If it has, try restarting the site or even the server.
