To enable the object cache, set up the WP_REDIS_CONFIG constant.

[birk]

• Failed to locate and load object cache API"

The plugin has been updated now.
Add this code in your wp-config.php before installing the plugin.

define(‘WP_REDIS_CONFIG’, [
‘token’ => ‘e279430effe043b8c17d3f3c751c4c0846bc70c97f0eaaea766b4079001c’,
‘host’ => ‘127.0.0.1’,
‘port’ => 6379,
‘database’ => 0, // change for each site
‘maxttl’ => 3600 * 24 * 7, // 7 days
‘timeout’ => 1.0,
‘read_timeout’ => 1.0,
‘split_alloptions’ => true,
‘debug’ => false,
]);
define(‘WP_REDIS_DISABLED’, false);

Still not working

I am getting this error

Also when you say DB → 0 (change for each site) What does 0 defines? And how to change for different sites? I have around 20 database. How does the script calculates and will understand which to connect with? Numeric DB makes it difficult.

The plugin doesnt start thats the main priority

[birk]

Yes, same error for me. Really hoping to have this resolved.

[Abhushek]

Is there any solution for this or should I remove this plugin from my website?

[birk]

Install on the fresh wp works, but can’t figure out what is the problem with the existing site.

[ProfessorZer0]

@FestyBot @Steve Any update on the same?

[birk]

Not the best fix, but managed to get it working with changing the object-cache.php in the /wp-content/

defined('ABSPATH') || exit;

if (version_compare(PHP_VERSION, '7.2', '<')) {
    return require_once ABSPATH . WPINC . '/cache.php';
}

if (defined('WP_REDIS_DISABLED') && WP_REDIS_DISABLED) {
    return;
}

if (! empty(getenv('WP_REDIS_DISABLED'))) {
    return;
}

$customRedisPath = WP_CONTENT_DIR . '/plugins/cacheboost-pro/api.php';
if (is_readable($customRedisPath)) {
    include_once $customRedisPath;
    return;

error_log('objectcache.critical: Failed to locate and load object cache');
