Set cache:
$e107cache = e107::getCache(); $e107cache->setMD5('your hash'); $e107cache->set('your tag', $cache_data);
Get cache:
e107::getCache()->setMD5('your hash'))->retrieve('your tag');
In fact, I have never notice this because with WP plugin it is free. I will see what it does after free trial.
Well it's nice but 10 dollar a month for a business use pro domain... that costs more than the hosting :-(
And yes, it works very nicely... I use it long time. Just first or second time used on e107 site.
