Scripting/PHP issue

Hi. I seem to be having problems with. romantic-cottages.com.au
Only the home page is showing.
Please see Crazy Domain’s reply to this issue below:
In addition I uploaded the recent version of Enfold via FTP. All good but it doesn’t show in the Themes section of my WP dashboard so I can’t activate it.
I am currently using an old theme called DARE.
