Fatal Error: Purge All Caches

I can empty the opcode cache and the disk cache individually but when I select the option to empty all caches except CloudFlare -or- I select Save All Settings and Purge Cache, I get a fatal error:

Fatal error: Uncaught Exception: unknown engine in /home/taastrat/public_html/wp-content/plugins/w3-total-cache/Cdnfsd_Core.php:48 Stack trace: #0 /home/taastrat/public_html/wp-content/plugins/w3-total-cache/Cdnfsd_CacheFlush.php(199): W3TC\Cdnfsd_Core->get_engine() #1 /home/taastrat/public_html/wp-includes/class-wp-hook.php(286): W3TC\Cdnfsd_CacheFlush::w3tc_flush_execute_delayed_operations(Array) #2 /home/taastrat/public_html/wp-includes/plugin.php(203): WP_Hook->apply_filters(Array, Array) #3 /home/taastrat/public_html/wp-content/plugins/w3-total-cache/CacheFlush_Locally.php(253): apply_filters(‘w3tc_flush_exec…’, Array) #4 /home/taastrat/public_html/wp-content/plugins/w3-total-cache/CacheFlush.php(188): W3TC\CacheFlush_Locally->execute_delayed_operations() #5 /home/taastrat/public_html/wp-includes/class-wp-hook.php(284): W3TC\CacheFlush->execute_delayed_operations() #6 /home/taastrat/public_html/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(”, Array) #7 /home/taastrat/public_html/wp-includes/plugin.ph in /home/taastrat/public_html/wp-content/plugins/w3-total-cache/Cdnfsd_Core.php on line 48

Everything had been working fine until I did a few tweaks with Preview mode enabled. I deployed the changes and Preview mode is no longer active. One change I made for which I can not find an unlink option is the linking to WordFence.
