I thought I'd post something on the forum to see if anyone had a solution and so at least there is online record of this error note as I had so much trouble trying to google the solution (search results brought up all other websites that have this error note).
We have a Managed Wordpress hosting account and intermittently get this error notice appear before our content (it appears repeated about 30-40 times).
Warning: apcu_fetch(): Function spl_autoload_call() hasn't defined the class it was called for in /wp-content/object-cache.php on line 1905
My best guess in searching online, is something is happening on GoDaddy's end, as I don't have a caching plugin setup. I also know phoning them may be frustrating as I can't always duplicate it. Anyone else have this error and have a solution?
