I was having white screen errors on a client's site, vibramed.net. I turned debugging on and found that I was getting an error in wp-content/object-cache.php on line 242
return $wp_object_cache->incr2( $key, $n, $group );
There is no function incr2() to reference, but there is a incr() function. Here's the fix:
return $wp_object_cache->incr( $key, $n, $group );
This is some sort of caching file provided by GoDaddy as denoted in the header:
/* * Plugin Name: APC/APCu/Redis Object Cache - transitional * Description: APC/APCu/Redis backend for the WP Object Cache. * Version 1.0 * * @Author James Dugger * @copyright 2017 GoDaddy Inc. 14455 N. Hayden Road Scottsdale, Arizona */
Can anyone provide any insights on to why it's there, what it's doing, or why it tries to reference incr2() which is a function that doesn't exist?
