Disqus Browser legacy error

Hi, I received a couple of comments today via the Disqus system, I logged in to WordPress to approve them and then visited the page on my site here only to find this message.

This page is forcing your browser to use legacy mode, which is not compatible with Disqus. Please see our troubleshooting guide to get more information about this error.

I’ve had a look at Disqus help and found nothing and also Googled for an answer but the only thing I’ve come across is a few others with the same issue.

Please can someone help?
