In reply to: [Patreon WordPress] Version 1.5.7 – Critical Site error

Plugin Contributor CodeBard

You didnt see a warning that comes out if your site is using api v1, saying that it would cause errors then? It appears during post sync setup and also in post sync section in options page.

https://www.patreondevelopers.com/t/how-to-upgrade-your-patreon-wordpress-to-use-api-v2/3249

In any case, the above tutorial will help you upgrade to v2 to fix the error and start using post sync.

The plugin uses Patreon avatar if no avatar is present. We are aware of the gravatar situation and this will be looked into in the next few weeks.

This was already resolved Sascha – you can just delete the existing plugin and reinstall 1.5.6 and it should work.

Chasing that particular error message did not avail, neither playing with the cluster configuration.

Instead, i moved to using redis + sentinel, configured it without password (accessible only in-cluster) and configured the plugin to use sentinel port and read only port for servers.

Now it works and properly stores keys in db. The config i used:

define( 'WP_REDIS_CLIENT', 'predis' );
define( 'WP_REDIS_SENTINEL', 'mymaster' );
define( 'WP_REDIS_SERVERS', [
    'tcp://redis-headless:26379',
    'tcp://redis-headless:6379',
] );

define( 'WP_CACHE', true );
// define( 'WP_REDIS_CLIENT', 'pecl' );
// define( 'WP_REDIS_PASSWORD', 'SOMEPASSWORDHERE' );
define( 'WP_REDIS_DATABASE', '0' );
define( 'WP_CACHE_KEY_SALT', 'SOMEKEYHERE' );
define( 'WP_REDIS_SELECTIVE_FLUSH', true );

This uses Bitnami’s redis helm chart below.

https://github.com/bitnami/charts/tree/master/bitnami/redis

Installed with…

helm install /root/custom-chart-location -n redis -f /root/custom-chart-location/values.yaml –set cluster.enabled=true –set sentinel.enabled=true –set usePassword=false

The values.yaml has Bitnami’s production values, except with network policy disabled.

Redis client at web nodes is installed via pecl. Version of php-redis installed is 5.2.2

These may help somebody.

Using

define( 'WP_REDIS_CLUSTER', [
    'tcp://redis-cluster:6379?database=0&alias=node-01',
] );

Instead of…

define( 'WP_REDIS_HOST', 'redis-cluster' );

I get…

Connection Exception: Couldn't map cluster keyspace using any provided seed (RedisClusterException)

I refreshed the site’s pages and visited some other urls in order to effect a cache read/write after flushing the db.

The thing is that the plugin seems to be able to see the redis server and ping it, right? It returns 1. And when i was using another version of Redis client (phpredis) it was ponging to ‘ping’. So connectivity should be there? Or is there any other particular pitfall that mmay be aside from connectivity?

Im wondering if this has anything to do with Bitnami’s Redis cluster for Kubernetes.

The later bit of code prints out absolutely nothing. Not even an empty array.
