The issue isn't with the problem reported by Microsoft. That's an issue if the Javascript actually removes elements from the page that haven't been loaded. The way Facebook does it's Javascript, it doesn't remove any elements from the page that it itself doesn't create.
Please send a link, and if you can PM us a super admin account so we can enable the plugin, that would help. Another thing you may want to try is to disable any compression or optimization scripts. Mainly, anything that does GZip'ing, as is the page is malformed (from a PHP warning or notice), you can also get the operation aborted. If you do, and you don't see the Operation aborted problem, look for messages in the output. Another alternative is to disable error reporting to prevent those messages. Since we haven't seen your page, I don't know if you have any of these things (error reporting or GZip compression) enabled.
Thanks!
