  1. few weeks ago we upgraded mysql server from 5.5 to 5.6

  2. on 1st server few days ago (5May) I reboot mysql server , after this customer reported that some database data table not load to their site . (mostly phpfox - also few in other scripts) - also new data not submitted to database

  3. I was reinstall mysql - disable cloudlinux - cagefs ... but problem not resolve. also rebuild php

  4. after above , I move that database to remote-mysql-test-server with same Mysql version (5.6) and problem resolved. So I found this problem mysql related

  5. yesterday in an other server like above (server B - that mysql upgraded from 5.5 - 5.6 few weeks ago) when mysql server restart , same problem occurred . for example when I answer ticket (WHMCS) , this date not submitted to ticket ... some clients can't update their site .

few website error like this : SQL] [1364] Field 'stat_time' doesn't have a default value STRING: INSERT INTO pn_statistics (stat_name,stat_value) VALUES ('Day-1394-02-24','0')

also in this server when I move database to remote-mysql-test-server this problem resolved.

  1. I speak with few system admin and they can't find my issue .

Any suggestion ?

I think your problem stems from a change in sql_mode.


Run this command

SET GLOBAL sql_mode = '';

Then, add this to my.cnf to keep sql_mode blank should you restart mysqld

sql_mode = ''

You do not need to restart mysqld since you set it globally

Seems like it would be better to figure what was wrong with the data (or whatever) and fix that. Turning off sql_mode may be "sweeping it under the rug".
