Troubleshooting

Symptom	Likely cause	Fix
“Add Bundle to Cart” stays disabled	Not every required slot is fully configured	Check that each unit has all its options set; an incomplete build cannot be added
A “stock conflict” warning appears	Two units picked the same variation and together exceed its stock	Change one unit to a different variation
“From £X” shows an old price	A component price changed but the bundle was not re-saved	Re-save the bundle, or re-save the component product
A bundle does not appear in the shop	The product is not Published	Publish the bundle product
The Bundle Items panel is blank	WooCommerce is older than 8.0	Update WooCommerce
A variable item shows “this combination is unavailable”	An older version with custom attributes	Update to the latest BundleBoss; recent versions match custom attributes automatically
Options do not update after picking a product	A JavaScript error on the edit screen	Check the browser console; make sure jQuery and Select2 load on the product edit page
The cart shows a stale price after editing	Browser caching	Hard-refresh (Ctrl+Shift+R) and retry
The “Restrict options” colour list looks empty	An older build with many options	Update BundleBoss; recent versions fix the admin option list width
