Shortcodes (tabs, accordion or other) don’t work in (sidebar) widgets

If the original shortcode appears on the public frontend

Please go to the Tag Groups Settings, Front end, Shortcode tab. Try if activating “Enable shortcode in sidebar widgets” helps.

If you see groups and tags, but not in tabs or accordion

Please go to the Tag Groups Settings, Front end, Shortcode tab. Make sure that “Always load shortcode scripts.” is activated.

If some tag clouds work, but others don’t, see this article.
