Change COLLATE for MySQL server before version 8.0
sudo nano /etc/mysql/my.cnf
[client]
default-character-set = utf8mb4
[mysql]
default-character-set = utf8mb4
[mysqld]
character-set-client-handshake = FALSE

Fix MySQL Error: Got a packet bigger than 'max_allowed_packet' bytes
Change the my.cnf or my.ini file (usually found in /etc/mysql/) under the mysqld section and set:
max_allowed_packet=100M
or you could run these commands in a MySQL console connected to that same server:
set global net_buffer_length=1000000;
set global max_allowed_packet=1000000000;
