Hi Guys,
I have had this issue before and it was a jQuery error, but I have searched my site and can't seem to find any errors being generated.
Basically if a form has conditional logic in it then it isn't being displayed.
For the time being I have just removed it from any public forms but have set up this page to show the error:

Any help would be great.
