Chronoconnettivity visible to guest users

I've tryed CC end everything was fine except that the form is shown correctly ONLY to registered users. in the case of guest users the following error is shown:
Fatal error: Cannot access empty property in /web/htdocs/www.ilpulcino.org/home/components/com_chronoconnectivity/chronoconnectivity.html.php on line 191

One thing: the table to which the form is linked does not have a primary key (a warning is shown every time a save the form).

Probably I'm missing something...😟

Thanks for your help!

Hi Andrea,

the table MUST have a primary key with auto increment for data insertion!

please fix this and see if the above error still exists ? and check if you set Guests to be able to insert data ?
