- 16. Because... • Not every site can be fully cached • e.g. membership sites • e.g. e-commerce sites • Even when full-page cache is present... • a missed request will take longer or even fail • There is always /wp-adminthat cannot be cached 16
- 17. So we need to take the harder path... 1. Trial and error method • theme/plugin conflicts may get skipped • inconvenience to the users if site is live 2. Debug like a hero! 17
