Configure cache correctly

It’s mainly about Woocommerce

The only important things is don’t toggle the cache on and off willy nilly in production, ideally just leave it on.

If you must disable it temporarily, it’s crucial that the cache is flushed right after disabling the cache drop-in it to avoid stale data in the cache.

Object Cache Pro does all of that for you, Redis Object Cache tries to but isn’t as bulletproof.

Good morning Till,

many thanks for your response. Where is the easiest place to send you a message?

Thank you and best regards Carsten

Via the little chat box on objectcache.pro ??

Good morning,

I would like to use the free version first to test it.

Is it enough to add the following line to wp-config.php?

define( ‘WP_CACHE_KEY_SALT’, ‘euergeheimerkey:’ );

And are special characters allowed in the password?

Thank you and best regards Carsten

Configuring Redis Object Cache is more complicated than that. It’s best to follow the installation instructions and configuration guide: https://github.com/rhubarbgroup/redis-cache/blob/develop/README.md

Thanks for the link. Unfortunately, since I’m not an expert, I activated the standard settings.

I’m mainly concerned with Woocommerce

Status: Verbunden ist alles was du brauchst.

Falls du mehr als eine WordPress Installation auf dem selben Server hast, dann musst du für jede Seite eine andere WP_REDIS_DATABASE Nummer verwenden.

Unfortunately, it is actually web hosting
