Trouble Saving Fusion Builder Edits

Hey,

I have been trying to add a new page to our website but I am unable to add and save any elements using the Fusion Builder.

When I open the edit dialog box to change text or design options it functions as usual until I go to save or close where the save, cancel and close buttons do not respond to clicks.

I have updated all my plugins and am using 4.9.6 version of WP. I have even deactivated and reactivated my plugins.

Does any one have any solutions or ideas? I have tried this in 3 browsers (Chrome, Firefox and Internet explorer) and I am having the same issue in all.

The page I need help with: [log in to see the link]
