Support » Plugin: W3 Total Cache » PHP Fatal error

  • I moved my WP to a new hosting with nginx and PHP7. When I try to empty only the disk cache
    (w3tc_flush_file) I see a blank page. I found this on error.log:

    2016/12/26 22:01:19 [error] 11916#11916: *3 FastCGI sent in stderr: “PHP message: PHP Fatal error: Uncaught Error: Call to undefined method W3TC\Generic_AdminActions_Flush::flush_pgcache() in /apps/webserver/mydomain.com/httpdocs/wp-content/plugins/w3-total-cache/Generic_AdminActions_Flush.php:250
