# Best Practices and Troubleshooting Checklist

## A checklist for diagnosing limit issues

When limits in [Maximum Products per User for WooCommerce](https://wpfactory.com/item/maximum-products-per-user-for-woocommerce/) do not behave as expected, work through this checklist before opening a ticket. Most issues come down to configuration, caching or counting settings.

### Diagnostic checklist

1. **Update first:** make sure you run the current plugin version and that it is tested with your WooCommerce and WordPress versions.
2. **Check the counting basics:** in **WPFactory > Max Products per User > General**, confirm the **Mode**, **Date range** and **Order statuses** match your intent.
3. **Confirm the limit level:** All Products (free) versus Per Product / Per Taxonomy (Pro). A per-product limit needs those Pro options enabled.
4. **Recalculate after changes:** re-run **Tools > Recalculate sales data** whenever you change Mode, Date range or Order statuses, and after installing on an existing store.
5. **Test in isolation:** switch to a default theme and disable other plugins to rule out conflicts.
6. **Clear caches:** page and object caches can serve stale cart or limit states.
7. **Use real test accounts** for each role to verify per-role and per-user limits.
8. **Check time-based resets:** confirm the store timezone, WordPress time settings and, if needed, **Advanced > Current time offset**.
9. **Keep a staging site and backups** before updates so a broken checkout never reaches customers.

**Tip:** if you use the Pro Formula section, keep your rules documented in an external sheet so they are easy to review and restore.
