Creating Blog Post from Front End issue

I'm having an issue with EasyBlog from the FrontEnd creating a post. I am getting the screen (attached) when I click on the Pencil to create a post. It appears it could be conflicting with the Supra RT Theme?

The site is used for our team website on our internal network so unfortunately I am unable to get you access since its behind firewalls and the only way I can reach it is via VPN.

Anything you can suggest I would be happy to try. Thanks
