Widget does not appear: Confirm the module is published, assigned to the current menu item, placed in an existing template position, and not hidden by URL exclude patterns.
Agents do not appear: Confirm at least one agent has a name and a valid phone number. Check department filter and schedules.
Only fallback appears: All agents are offline or filtered out. Set one agent to Always Online for testing.
WhatsApp link does not open: Check the phone number format. Use international format with country code.
Email fallback fails: Check Joomla global mail settings and fallback recipient email.
Add button missing in Agents tab: Clear Joomla administrator cache and refresh the module edit screen. The Agents field uses Joomla's repeatable subform layout.
Styling does not update: Clear Joomla/browser cache and check whether template CSS is overriding module CSS.
Analytics events missing: Confirm dataLayer exists when GTM support is enabled, or listen for the browser CustomEvents.
