Error when Enabling XCache

[mynsc]

Getting the following error when trying to enable XCache from System -> Advanced Configuration -> Data Storage -> Caching Method, after uploading constants.php. It does not matter if Data Storage Method is set to File System or MySQL Database:

Fatal error: Uncaught exception 'ErrorException' with message 'xcache_set(): XCache var cache was not initialized properly.

Line 66 is:

		return (bool) xcache_set( \IPS\SUITE_UNIQUE_KEY . '_' . $key, $value );

In case it helps, php.ini shows the following info regarding XCache:

I've also searched for any specific PHP errors, with not much luck. I've looked at /usr/local/apache/logs/error_log and didn't see anything relevant.

I've also checked /usr/local/cpanel/logs/error_log and did find this, however not sure how relevant it is:

The constants.php file I get is

<?php


define( 'STORE_METHOD', 'FileSystem' );
define( 'STORE_CONFIG', '{"path":"/home/user/public_html/datastore"}' );
define( 'CACHE_METHOD', 'Xcache' );
define( 'CACHE_CONFIG', '[]' );
define( 'CACHE_PAGE_TIMEOUT', 180 );
define( 'SUITE_UNIQUE_KEY', 'some_unique_key_here' );

Could anyone give any hints as to why this error is occurring and what can be done about it?
