Hi,
after an easy installation an customization I wanted to add events.
When I use administrator backend, the events do save to DB, are shown in the backend list.
When I use public frontend, JS “Reference security violation error” error occures on load, no events are displayed and the AJAX does not save the new events to DB.
Please, can somebody help? Otherwise perfect component, love it 
Hello,
Please specify what plugin do you use (Joomla, Wordpress).
Also make sure that site url in the configuration and in the actual address bar are the same.
For example:
configuration: some-site.com
your actual address: some-site.com
In such case you are making an ajax request form some-site.com to the some-site.com/calendar/some_script.php and that’s can result in security violation error.
Best regards,
Ilya
