XF 1.2 Memcached problem

[TPerry]

I have just installed memcached on my dedicated server (Debian Wheezy) and enabled (per the manual) the backend.
When I go to the site I now get

An exception occurred: The memcache extension must be loaded for using this backend ! in /var/www/twowheel/library/Zend/Cache.php on line 209

The PHP5 module looks to be loaded


I've given it 512MB for the cache in memcached.conf.

When checking netstat I get this

netstat -tap | grep memcached
tcp        0      0 localhost:11211         *:*                     LISTEN      3542/memcached

I've restarted php5-fpm numerous times as well as nginx.

I've tested to see that it is loaded using a test php file containing

<?php
$mc = new Memcached();
$mc->addServer("127.0.0.1", 11211);
.
$result = $mc->get("test_key");
.
if($result) {
  echo $result;
} else {
  echo "No data on Cache. Please refresh page pressing F5";
  $mc->set("test_key", "test data pulled from Cache!") or die ("Failed to save data at Memcached server");
}
?>

and I get the test data pulled from Cache! statement when browsing to it and refreshing - which I believe indicates that the cache is working.

Any hints on where to look?

This was resolved by further testing by me. In addition to doing having to do

aptitude install memcached php5-memcached

you have to also do

aptitude install php5-memcache

It'll be an interesting experiment. back in the heyday when I joined the team, you would have had an answer from matt within an hour.

Well, it's rocking along two months later and there is STILL no reply to it. And folks ask why it's worth going with a paid script over the free ones (like myBB). THIS is why. You wouldn't go two months without a reply on the official support forum of xenForo. Even if it was to say "Sorry, can't do that".

Ah. Stupid iptables rules. It works now.

But I'm getting error:
