Recent posts widget does not show

Hi,

I have a default sidebar on the site. I can put text widgets, calendar widget, but the built-in recent posts widget from wordpress doesn’t show on single event page.

They will show on other pages including the events listing, but it doesn’t on the single event page.

I’ve tried the built-in ‘default’ wordpress widget menu and it works..

Any ideas why this specific widget won’t show up?

If I put some text widget under the recent post widget, they will show. This one just gets ‘skipped’ …
