[Solved] MySQL ERROR 1231 (42000):Variable 'character_set_client' can't be set to the value of 'NULL'
If you try to import dumped file, and there is such an error, try using mysql console with options and then import sql file
mysql -u root -p --max_allowed_packet=6400M
Troubleshoot
If you haven’t acess to console or the previous doesn’t work
set global max_allowed_packet=10000000000;
