gotequity on "[Plugin: WP-FFPC] Wordpress database error Table doesn't exist."

I understood your instructions, Peter; loaded wp-ffpc-class.php into Notepad++ from a fresh download of v1.7.7 directly from the wp-repo, modified lines 1145 & 1146 as instructed, and uploaded the revised file to the server. Went back into network admin, reactivated WP-FFPC, saved settings (APCu), and received the fatal error after clicking precache.
