The only solution that worked for me was to go to the File Manager through our web host, delete the events list folder, and then reinstall the previous version of the plugin (6.8). The old version still works, and it retained all of the event data that I’d entered previously.
Same error here:
Fatal error: Call to undefined function get_user_locale() in /home/content/95/11651295/html/wp-content/plugins/event-list/event-list.php on line 87
