If your WordPress blog gives you a failure about curl_init and you are absolutely sure you have curl support enabled in PHP, and you are using wp-hashcash, than change the version check period.
Look for a line beginning with “if(!array($update) || empty($update[‘last’]) …
In that line is a figure “86400”. Change that to a very large number, like 999999999. That would be enough for feifei to get their site back up.
