Setting
What it does
Quantity stepper
Adds +/- buttons that move by the step and stop at min/max.
Replace theme stepper
Turn on only if your theme’s own +/- buttons ignore the step.
Live inline guidance
Shows the hint and live validation under the quantity field.
Shop / archive “Add to cart”
Add the minimum valid quantity (default) or Link to the product page instead.
Validate AJAX add-to-cart
Keep on. Validates grid and carousel buttons server-side.
WarningTurning off Validate AJAX add-to-cart does not turn off validation in the cart or checkout: those are always enforced.
Advanced
Setting
Use when
Hook priorities
Another plugin also filters quantity args, validation or prices and you need to run before/after it. Higher number = later.
Load assets everywhere
Your theme renders add-to-cart forms on pages the plugin does not recognise (landing pages, page builders).
Delete data on uninstall
You want all rules and settings removed when the plugin is deleted. Off by default.
