I've been trying to get help from the Oxwall development/tech folks on this for over six months now and could really use some help. I suspect it's a simple fix...

When some users (including me from one particular computer, only) try to log in to our site, they get a plain red "error" message and the little wheel next to sign in shows it clocking/spinning but it happens immediately (not after clocking for a while). Once that happens, even when refreshing and going back, you can't log in at all. Only some users are affected but it prevents them from logging in.

HOWEVER - when logging in from our sitename.com/sign-in, the error NEVER comes up, even immediately after experiencing the error on the primary sign-in page.

I checked javascript console in chrome and this is the error I got:

XMLHttpRequest cannot load https://www.sitename.com/base/user/ajax-sign-in/. Origin http://www.sitename.com is not allowed by Access-Control-Allow-Origin.

Uncaught error ow.js:1415

XMLHttpRequest cannot load https://www.sitename.com/base/ping/index/. Origin http://www.sitename.com is not allowed by Access-Control-Allow-Origin."

I put in a ticket with my server host and they replied with the following:

"This looks to be an issue with scripting. We do not currently provide support for this. Here is some documentation I found that may help you to resolve this. You will need to work with a developer for support.

Can anyone help me with this?
