I am having the same issues as the "pinesystem" user, I noticed that on our website using IE 8 and Jomsocial that no one can login anymore. The problem is only occurring with IE 8, and our website is a production site so we are getting a large number of customer service complaints regarding this.Our site is
www.icoupononline.com, and you can check out the issue if you would like.
Our subscription just expired but we can get a new one to apply the upgrade if you think it will solve the problem. At this point we would just like to narrow down if this is the root of the problem, and solve it.
We truly appreciate the help, and will await your response on this issue. All the best!
