Support » Plugin: W3 Total Cache » Error clearing caches in W3 Total Cache plugin

  • Hi expert,

    I am encountering problem clearing cache in w3 total cache plugin while doing my web design. Below is some background. I have installed W3 Total Cache plugin, activated the cloudflare extension, however, it is throwing error as below. Also, i noticed that the plugin does not increase the speed at all after check with Google Speed test. Is some configuration that i had done wrongly?

    my site –

    Fatal error: Uncaught exception 'Exception' with message 'unknown engine ' in /home/ab90275/public_html/wp-content/plugins/w3-total-cache/Cdnfsd_Core.php:48 Stack trace: #0 /home/ab90275/public_html/wp-content/plugins/w3-total-cache/Cdnfsd_CacheFlush.php(199): W3TC\Cdnfsd_Core->get_engine() #1 [internal function]: W3TC\Cdnfsd_CacheFlush::w3tc_flush_execute_delayed_operations(Array) #2 /home/ab90275/public_html/wp-includes/class-wp-hook.php(298): call_user_func_array(Array, Array) #3 /home/ab90275/public_html/wp-includes/plugin.php(203): WP_Hook->apply_filters(Array, Array) #4 /home/ab90275/public_html/wp-content/plugins/w3-total-cache/CacheFlush_Locally.php(253): apply_filters('w3tc_flush_exec...', Array) #5 /home/ab90275/public_html/wp-content/plugins/w3-total-cache/CacheFlush.php(188): W3TC\CacheFlush_Locally->execute_delayed_operations() #6 [internal function]: W3TC\CacheFlush->execute_delayed_operations() #7 /home/ab90275/public_html/wp-includes/class-wp-hook.php(296): call_user_func_array(Array, Array) #8 /home/ab90275/publi in /home/ab90275/public_html/wp-content/plugins/w3-total-cache/Cdnfsd_Core.php on line 48
