Disable MySQL strict mode!

by

We recently migrated WHMCS to latest CentOS 7 server with cPanel. The WHMCS ClientArea showed White screen when “Client logins were used”. We found that the server had MySQL strict mode enabled which was causing this problem.

I disabled MySQL strict mode as below :

Edited /usr/my.cnf and changed below value :

sql_mode=NO_ENGINE_SUBSTITUTION,NO_AUTO_CREATE_USER

Restarted MySQL :

/scripts/restartsrv mysql

voila this worked…… earlier I was trying to change sql_mode under /etc/my.cnf however found MySQL is using different location /usr/my.cnf
