can I know if you used that using events widget? also, maybe you can try wp plugins shortcode in text widget
No, it worked before with simply a wp-text widget. After the upgrade to 5.3.9 it stopped working.
Other shortcodes in widgets are still working, so it is probably resulting from the upgrade in Events Manager
hmm, maybe your theme is allowing shortcode on text widget since it doesn’t work on my test site using twenty twelve theme. however, is everything working okay except shortcode events_list_grouped?
Hmm… no, I tried other shortcodes – not working either.
Is there another way to display grouped events in a widget? Can I customize the events widget?
OK, that did the trick. I included these two lines in my functions.php
add_filter( 'widget_text', 'shortcode_unautop');
add_filter( 'widget_text', 'do_shortcode');
But I still wonder why it did work before…
Thanks anyway, Angelo!
