This is an odd one. The login box on the side will not login someone in. It sends the customer to the actual login page, and says "There was a security error when trying to login." You can login from there, and you can click the login link at the top and login from that page, just not from the sidebox. I'd like to leave it on, simply because it has account links there when a customer is logged in, but I can't figure out what's causing the error or even what the error is. I'm running the latest version of ZenCart, using SSL, with no mods that touch the login procedure. The only actual mods I have add a couple of basic sideboxes with HTML in them.
