Submit Event page not displaying
Hi Don
I can tell you that's not a bug of Events Booking. It is a bug of Gantry framework from Rocket theme (I had clients with this issue in the past).
Basically, it seems Gantry Framework try to check if there is any output "like" twitter bootstrap, it will call a function which is only available in Joomla 3.0.x

.
In this case, please send me FTP account of your site. I will edit the code of gantry plugin alitle and the issue will be solved .

I appreciate the developer's offer to edit the Gantry source code, but this is not a "solution;" the next Gantry update will overwrite the modification and my clients will be blocked from adding events on their Websites from the front-end.
