I started building a website in Oct. 2013 which originally had WordPress 3.7.1 and was on a server with PHP 2.27. I installed version 0.9.3 of W3 Total Cache and it worked fine.
A few days ago we moved the site to a server running PHP 2.42. WordPress has been updated to version 3.8. The plug-in was deactivated when we moved the site. Today I tried to activate it and got this error message:
Plugin could not be activated because it triggered a fatal error.
Fatal error: Call to undefined function apc_fetch() in /home/amerispe/public_html/dev/wp-content/plugins/w3-total-cache/lib/W3/Cache/Apc.php on line 171
Here is the code this refers to:
// if we have expired data - update it for future use and let
// current process recalculate it
$expires_at = isset($v['expires_at']) ? $v['expires_at'] : null;
if ($expires_at == null || time() > $expires_at) {
$v['expires_at'] = time() + 30;
apc_store($key . '_' . $this->_blog_id, serialize($v), 0);
$has_old_data = true;
return array(null, $has_old_data);
}
// return old version
return array($v, $has_old_data);
}
I checked with the hosting company. Nothing they're doing is affecting this.
I deleted all the plug-in files via cPanel and reinstalled the plug-in. That didn't help.
Anyone know why I'm getting this error? Is it because the plug-in hasn't been updated to 3.8 yet?
I will appreciate any help. I am supposed to take this site live this week, and can't do so without optimizing it. Thanks!
