Hello onesourcebackground I am getting the same error, and have no idea why, the error is random at showing up and once i got multiple errors like the folloiwng:
Warning: Class __PHP_Incomplete_Class has no unserializer in /home/content/p3pnexwpnas10_data01/33/2567433/html/wp-content/object-cache.php on line 520

No idea why i went to those lines in the php but I dont know enough if it is wrongly written, but im sure it has to do with wordpress new version.
I had it for my site tbsmo.com
