Kill Switch & Safe Fallback

Kill switch

Open System > Manage > Plugins > System - JHFB and switch Kill switch on. All output stops at once, on pages with Theme Takeover and for the JHFB module, and your theme's own header and footer show. Switch it off to bring your designs back.

Disabling one item

Unpublishing or deleting a header or footer brings back your theme's own header or footer exactly as it was. Joomla's page cache is cleared whenever you change an item, so the change shows straight away, even with the System - Page Cache plugin on.

Safe fallback

If something fails while the extension is rendering (for example the design page is missing, or the page builder cannot be reached), the error is logged and the visit carries on with your theme's own header and footer. A visitor never sees a broken page because of this extension.

Disabling the System - JHFB plugin has the same effect as the kill switch.
