wp_ob_end_flush_all and wp_suspend_cache_addition()
Im getting these two errors and my site is stuck keeps giving me a 500 error.
The 2 errors are :
PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'wp_ob_end_flush_all' not found or invalid function name in /public_html/wp-includes/class-wp-hook.php on line 286 PHP Fatal error: Call to undefined function wp_suspend_cache_addition() in /public_html/wp-includes/cache.php on line 402
Weird note: I accidentally moved all the files into a subdirectory ie. /public_html/examplefolder/allwordpressfiles. and the site worked (without any of the images or links working obviously) but it didn’t return a 500 error.
So is there something wrong with my public_html folder I check permissions and they were 755.
