errors on all sites

After installing some updates last night, all of my sites on my multisite installation broke with an error on them like the one below, which was caused by the advanced cache.
I renamed the advanced-cache.php file initially to solve the problem, but the issue returned after I made a new post.
So I then went into each site and cleared the cache, which also got rid of the error.

Fatal error: Uncaught Error: Call to undefined function absint() in /home/zenfusio/multisite1/wp-includes/load.php:817 Stack trace: #0 /home/zenfusio/multisite1/wp-content/advanced-cache.php(30): get_current_blog_id() #1 /home/zenfusio/multisite1/wp-settings.php(84): include(‘/home/zenfusio/…’) #2 /home/zenfusio/multisite1/wp-config.php(98): require_once(‘/home/zenfusio/…’) #3 /home/zenfusio/multisite1/wp-load.php(37): require_once(‘/home/zenfusio/…’) #4 /home/zenfusio/multisite1/wp-blog-header.php(13): require_once(‘/home/zenfusio/…’) #5 /home/zenfusio/multisite1/index.php(17): require(‘/home/zenfusio/…’) #6 {main} thrown in /home/zenfusio/multisite1/wp-includes/load.php on line 817
