Caching in XF2...

[Jaxel]

Below is my cache settings for XF1... how would I set this up in XF2?

$config['cache']['enabled'] = true;
$config['cache']['frontend'] = 'Core';
$config['cache']['frontendOptions'] = array(
    'caching'                    => true,
    'lifetime'                    => 3600,
    'cache_id_prefix'            => 'calibur_'
);
$config['cache']['cacheSessions'] = true;

$config['cache']['backend'] = 'Memcached';
$config['cache']['backendOptions'] = array(
    'compression' => false,
    'servers' => array(
        array(
            'host' => 'localhost',
            'port' => 11211,
            'persistent' => true,
            'weight' => 1,
            'timeout' => 5,
            'retry_interval' => 15,
            'status' => true,
        )
    )
);

But what is "Core"?

And what about all my configurations to Memcache?

 

[Jaxel]

Just using the default settings:

$config['cache']['enabled'] = true;
$config['cache']['sessions'] = true;
$config['cache']['provider'] = 'Memcached';
$config['cache']['config'] = [
    'server' => '127.0.0.1',
];

Gives me the following error:

Fatal error: Uncaught exception 'LogicException' with message 'Cannot load Memcached cache provider without Memcached' in /src/XF/CacheFactory.php:150 Stack trace:

I can't help you more than what the manual is telling us.
Maybe write a support ticket to the staff for the problem.

You do have both memcache & memcached PECL's loaded via PHP?
You do have a valid memcached server running?

You can make sure the memcache service is up and listening:

lsof -i :11211

If it's not something like "systemctl start memcached" will get it up. You'll probably want to enable it to auto-start upon system boot with "systemctl enable memcached".

To make sure you have the PHP module something along these lines will work on cPanel:

/opt/cpanel/ea-php72/root/usr/bin/php -m |grep memcache

The above assumes you're using PHP 7.2. You'll need to change it depending upon the version of PHP you're using.
