Multi-Language - "Home" button LINK alyways go back to default language

[pechesud]

I upgraded my TEST website from 1.39H to 1.55f, everything works fine after few adjustments. This website is configure to support English and French language, the default language is "English".

I have a issue about the "Home / Accueil" button, the URL don't take care of language setting, it always go back to default language in "English". No issue in 1.39H.





TEST WEBSITE URL : www.pechesudv155.owally.com

Version of Zen Cart: 1.55F
PHP version: 5.6.39 (phpinfo.php is avalaible)
SSL: Yes

Plugin: French Language pack made from "English version"

I suppose the home button link is define inside TLP_HEADER.PHP
Line: 47 <li><?php echo '<a href="' . HTTP_SERVER . DIR_WS_CATALOG . '">'; ?><?php echo HEADER_TITLE_CATALOG; ?></a></li>

My question is: How language code is set inside "home" button URL ? or Does someone else already had the same issue? how can I fix this ?

Thanks for your help
