Do you work on staging or my live store?

Staging first, always. We clone your store to a staging environment, turn full error logging on, and reproduce the bug there, never debugging blind on your live storefront. Once the fix is tested, we deploy it to live, refresh the vQmod/OCMOD modification cache, clear the OpenCart cache, and verify the fix in production with you. If you don’t have staging, we can spin one up.
