I create a new event in admin panel.
After clicking on any link translation, a pop-up window appears with an error 403.
In the previous version there was my event and fields for translation
Chrome Dev Tools: GET index.php?option=com_jevents&task=icalevent.translate&evdet_id=&ev_id=&pop=1&tmpl=component&lang=en-GB 403 (No event details passed in to translation script)
