This error is caused by an insufficiently large max_allowed_packet setting in your MySQL server's my.cnf file.

Solution: Increase max_allowed_packet variable.

Note: Make sure the variable is under [mysqld] section, not [mysql].

file path in linux OS : /etc/my.cnf

if you couldn't found the line in file simple add under the [mysqld] section

max_allowed_packet=64M

Note : Don't forgot to restart mysql and apache server
