Hi, Kjell. Some of our users are experiencing this error; sorry you’re one of them.
I marked this thread as Pending Fix, which means it should receive a reply once the applicable fix has been released. I cannot guarantee when it will be fixed as it’s in the development team’s hands. They need to assign it, code it, test it, and schedule it for release.
I apologize for this issue and appreciate your understanding and patience.
For now, please manually update the plugin: https://theeventscalendar.com/knowledgebase/manual-updates/
