There are some recommended settings in the Database settings.

First of all, we are NOT recommend to SQL Mode set STRICT_TRANS_TABLE. STRICT_TRANS_TABLE turned off.
So what should be inside SQL MODE?

sql_mode = ”;
or
sql_mode = ‘NO_ENGINE_SUBSTITUTION’;

Now, what we recommend:

default-storage-engine = InnoDB
collation-server = utf8_general_ci //Depend on Languages
character-set-server = utf8

The files contain the owner’s settings and permission configurations.

chown -R root:www-data

Now, follow these instructions:

cd
find -type d -exec chmod 755 {} \;

Certain folders and files require specific permissions, which may vary depending on your Vtiger version.
