Would it be possible for me to email you a username/password to log in and see the site? I can temporarily make the page published.
Unfortunately I cannot post it. Its work for a client and all the links and pages must be unpublished until its launched.
I was missing the “?” at the end.
?app_tab=true&fb_force_mode=fbml
instead of
?app_tab=true&fb_force_mode=fbml?
It hasn’t seemed to help the situation though. I am still getting the same error.
