SEO Facebook Comments Crashing My Blog

Hi, I’ve used SEO FB Comments before and it worked fine, but for some reason, now it’s crashing.

I have disabled all plugins and just activated SEO FB Comments, and the same problem occurred.

I have also tried 3 different themes and the same problem happens.

I have recorded a quick short video here to explain the problem I’m having.

If you know what may be causing this, please let me know as I really need to use the plugin on my site again.

Thank you
Gavin
