Troubleshooting
The drawer doesn't open
Check that the plugin is enabled, that Enable drawer is on, and that the page isn't listed in Exclude menu item IDs. Clear Joomla's cache and your browser cache.
The cart count in my header doesn't update
Enter your template's cart count selector in Header cart count selector on the General tab.
I see two cart buttons
On the Launcher tab, choose header or floating rather than both.
The package won't install
Phoca Cart Drawer needs Joomla 5 or 6 and PHP 8.1 or newer.
