I didn't configure the HTTPS on my domain so I'm not really sure where to start with this warning prompt that I only get on iOS Safari on my iPhone and iPad. I've never gotten this on a desktop with Mac Safari, Chrome, FF, or IE.
Can someone point me to a file on my ubuntu/apache EC2 server or somewhere on the site of my domain provider, GoDaddy, that deals with verifying certificates.
I found the link which solved my problem.
I needed to put BOTH .crt files from GoDaddy into my /etc/apache2/ssl folder on my apache EC2 server and add the following to my /etc/apache2/httpd.conf file:
SSLCertificateFile /etc/apache2/ssl/mysite.com.crt
SSLCertificateChainFile /etc/apache2/ssl/gd_bundle.crt
