This is all I can see. I create a superadmin account for ARTIO and sent info by email, can you please take a look? This is for a production site due for launch by the end of this month. You should be able to replicate the 500 error by simply logging into the frontend and clicking "reservations". You can see the user error by trying to make a reservation or create a customer on the backend...

So.....are you saying I should uninstall ARTIO Bookit2 and find another component??

I'm having the same issue. I installed Artio Bookit2 on Joomla 3.1..........I get a Global error when I try to make a reservation from the backend:

Error

setGlobalConfigByUserFromReservation(): No user Argument is object, shoul be array


I also get a 500 error when I LOGIN on the front-end or create an account:

Error: 500

TableSubject::bind(*NULL*)

This happens whether I use the Artio user module to login/create account OR if I use the Joomla module. The rest of the website is fine, but when I click on the menu item assigned to ARTIO it kicks the 500 error.
