Calendar Widget not showing the correct date after the new year

Hello all,

Hope I’ve posted this on the right forum, if not .. apologies. Here is my issue.

On the main page of our site, I have a Calendar Widget displayed on the sidebar, which worked fine until the end of 2020, but it would seem that it no longer is working since January 1rst 2021. It’s currently displaying the date as December 15 2020 instead of todays date (January 15 2021).

We are using it with the Events Manager. The events we created is showing the correct date (January 21rst). I went over the settings in the Event Calendar but could not find anything relevant.

I’ve disabled all the plugins with no effect.

The current date is showing correctly in the WordPress settings.

I’ve tried using another theme, but the date is still showing as December 15 2020.

I’ve tried looking at all the extra CSS, but cannot find anything relevant to the Calendar.

I’m at the end of my (short) rope. Any suggestions on what might be causing this would be welcomed.

Thanks
