I'm working on whmcs and it requires disabling MYSQL strict mode.
I searched about it and it says you can find it in my.ini or my.cnf.
My problem is that I can't find it in any place in file manager. Can Someone help me find and edit it?
You will not find my.cnf file in your File Manager. Generally it resides in /etc directory. If you are on shared server, you will not have access of this file.
If you have VPS/Dedi. Server, you can SSH into the server and edit this file. Use any editor like vi, nano to edit this file.
You will have to set blank in sql-mode i.e.
Then restart MySQL service.
