When I make a reservation and push the submitbutton, the following error happens.

ReferenceError: submitform is not defined
submitform(pressbutton);

I'm using Version 2.0.1 and Joomla 3.1.1
Any help would be great, thanks!

Hello,

Joomla 3.1 is not supported yet. There can be some changes what are not compatible with actual version of Booking. Book it! 2.0.0 was released for Joomla 3.0 and other versions 2.0.1 and 2.0.2 as well.

Joomla 3 should be stable from version 3.5. Then there should be no more these problems. We will try to prepare new release for 3.1 soon. But I don't know when it will be possible.

Hello Maju

I reinstalled Joomla 3.0 and setup all new, with Book it! 2.0.4. Unfortunately I get the same Error on the submitbutton, when I try to make a reservation.

Thanks for help, Nic!

I found the solution, in my Templatefile the "/media/system/js/core.js" was unset. Now the reservation works fine with Joomla 3 and Book it! 2.0.7.
