Cannot export entries #391

Hello,

the export of entries always fails with the error message

WebCalendar Error Fatal Error: Invalid form request

The variable $_REQUEST['csrf_form_key'] is empty, so preventHacking() fails.

Used version of Webcalendar is v1.9.1-82-g9b7b3a55 OS: Debian 11.7 with PHP 7.4.33
