Even though I type "http://aoafinc.org/wp-admin" into the address bar, it was turned into "https://aoafinc.org/wp-admin". Also, all the links to images on my site are "https" instead of "http". Since my SSL certificate has expired, all these images can't be loaded.
I just take over this website from someone and don't want to renew the SSL, also I am not very familiar with WP or SSL either, but I guess I don't have to manually edit all the image links, there should be somewhere on WP's back end to set the website as non-ssl and hopefully all links will become "http". And more essentially, why the browser is requesting HTTPS url even though I type in a HTTP url?
