Set vm.max_map_count to at least 262144

The vm.max_map_count kernel setting must be set to at least 262144 for production use.

How you set vm.max_map_count depends on your platform.

To view the current value for the vm.max_map_count setting, run:

$ grep vm.max_map_count /etc/sysctl.conf
$ vm.max_map_count=262144

To apply the setting on a live system, run:
$ sysctl -w vm.max_map_count=262144

To permanently change the value for the vm.max_map_count setting, update the value in /etc/sysctl.conf.

Solution

chown theaiops:theaiops -R * # Let Apache be owner
find . -type d -exec chmod 755 {} \; # Change directory permissions rwxr-xr-x
find . -type f -exec chmod 644 {} \; # Change file permissions rw-r–r–

This is a read-write permission error. Fix this by changing the "wp-content" folder's permissions to 755.

If this doesn't work checked the wp-config.php file and if it's not already defined, add

define('WP_TEMP_DIR', ABSPATH . 'wp-content/');
