 * Since I installed the update this morning, I get an error when trying to access
   the plugin page on my wordpress site –
    Fatal error: Call to undefined method
   W3TC\Cdn_Util::is_engine_fsd() in /home/a567627/public_html/wp-content/plugins/
   w3-total-cache/Cdn_Plugin_Admin.php on line 13
 * This error appeared after update to latest release of W3 Total Cache plugin.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferror-since-update-2%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * I have a similar error, it seems that the FSD CDN option is default “true” or
   checked even if you haven’t upgraded and don’t have that option (or want it).
   Since the field is locked, I am unable to turn it of, this may be why I am also
   getting a fatal error.
