Hi Tom,
I have the same problem with Carine (first you see an “ERROR {"cmd":"load","html": …“and after refresh all going fine). I host the script to 2 deferences hosted companies and in the first work fine, but in the second I get the ERROR. So I think is something with the hosting settings. Can you help me? What is the requirements that you must have in hosting settings (except php 5.2), in order to work fine the script?

OK, try this. Open web/conn/index.php and find the following line:

error_reporting( 22527 );

Change 22527 to 0 like

error_reporting( 0 );

Let's see how it goes
