[Plugin: Login With Ajax] Plugin not redirecting in internet explorer but works in chrome

Hi, I just installed the Admin bar along with the login Ajax plugin. I redirected all traffic for login to:
https://www.petsitclick.com/customer_portal.a5w?company=be051f43a22540d082224e460b608a5a

it is working fine in chrome but in explorer (I’ve tried many computers with different versions of ie) it goes directly to wordpress login. Is this an Admin bar problem or Ajax plugin? Can someone tell me what I might be doing wrong or how I can fix this?

I apologize if I have not put enough info in this post but I’m new to forums..
