I have a facebook app which is basically a job app. The job headline is linked up to a job details page. The page opens perfectly in Firefox, chrome and IE for me. But, one of our clients have pointed out that the page doesn't opens up in IE. What could be the possible reasons for this issue? If the page is refreshed, the the page comes up fine. Please find the link below for a screenshot...
I see that FB is running in secure mode, what means that https is activated. Do you have a SSL certificate for your target domain?
