Hi @Anton L

Thanks a lot for your reply. I went into the database > sys_localization_languages table, then changed the 'Name' value from 'us' to 'en-us'. It works. 'en' is used as lang in the 'HTML' tag. Thanks a lot.

Now I have two questions:

Question #1: With the change above, should I also need to change every instance of 'us' to 'en-us' in my new English (US) language module when creating it? or maybe, just changing the 'Name' value in the sys_localization_languages table is enough, it's the only thing that needs to be modified.

Example:

In language_module/install/config.php

Should I change:

'name' => 'xxx_us', To: 'name' => 'xxx_en-us'

'home_uri' => 'us', To: 'home_uri' => 'en-us',

in language_module//install/sql/install.sql:

Should I change:

INSERT INTO `sys_localization_languages`(`Name`, `Flag`, `Title`, `Enabled`) VALUES('us', 'us', 'English (US)', '0');

To:

INSERT INTO `sys_localization_languages`(`Name`, `Flag`, `Title`, `Enabled`) VALUES('en-us', 'us', 'English (US)', '0');

in language_module//install/sql/enable.sql

Should I change:

UPDATE `sys_localization_languages` SET `Enabled`='1' WHERE `Name`='us';

To:

UPDATE `sys_localization_languages` SET `Enabled`='1' WHERE `Name`='en-us';

in language_module//install/sql/enable.sql

Should I change:

UPDATE `sys_localization_languages` SET `Enabled`='0' WHERE `Name`='us';

To:

UPDATE `sys_localization_languages` SET `Enabled`='0' WHERE `Name`='en-us';

in language_module//install/sql/disable.sql

Should I change:

UPDATE `sys_localization_languages` SET `Enabled`='0' WHERE `Name`='us';

To:

UPDATE `sys_localization_languages` SET `Enabled`='0' WHERE `Name`='en-us';

Also should I rename all my app translation files within the English (US) language module (e.g.: /data/langs/bx_artificer/us.xml) from:

us.xml

to

en-us.xml

and in those xml translation file,

Should I change:

To:

"en-us" flag="us" title="English (US)">

Do I need to make those changes? Please advise.

Question #2: For testing purposes and as I am planing to create new language modules in the near future, I changed the value of 'Name' to 'fr-fr', 'fr-ca', 'es-es' and 'es-mx' in the `sys_localization_languages` table but nothing happened. The value of 'lang' in the HTML tag remains 'en'.

Why can't they change to "fr' or 'es' as 'en-us' does and changes to 'en'? Any idea?

Thanks
