"The page isn't redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
This problem can sometimes be caused by disabling or refusing to accept cookies."
I've tried using Chrome, cleared cookies, etc and been on the phone with Hostgator support several times. I've also deactivated all plugins and reactivated them one at a time.
One time I had to delete the site and start over (it was fairly new). Another time it started working, but I have no idea why. The latest time the support guy said that it would work on his end when he changed my permalink settings. I keep them at /%postname%/ so I definitely didn't want to change them.
It seems like this problem started around the time of the Wordpress update to 4.5.2, but it's not affecting every site. That's what stumps me.
Anyone else having this problem? I'd appreciate any advice.
