W3 Total Cache It is one of the best PluginCEs of optimization (SEO si server resource / page speed) For WordPress.
A few sites using this WordPress plugin I encountered errors like:
[Sat Oct 01 05: 41: 28 2011] [error] [client IP] PHP Fatal error: Call to undefined function w3_url_format () in / home /username/ Public_html / wp-content / plugins / w3-total-cache / lib / W3 / Plugin / PgCacheAdmin.php on line 213
Including specifically the error appears in the latest version 0.9.2.4 the W3 Total Cache.
For a blog owner who has cPanel for managing service Web Hosting or no access to Apache error LogsIt error is invisible. Not sure if it affects the smooth functioning of the plugin W3 Total CacheBut you should be eliminated.
