Plugin lang strings does not load properly throug i18N when admin log out

[jesusda]

There is no support for front end languages, but there are some hacks like setting $LANG in gsconfig.php
Or using i18n plugins

So, the bug must be inside the GS Blog plugin. Isn't it?

I've set $LANG in gsconfig.php typing:

define ('LANG', 'es_ES');

but nothing happens.

Is this the right way?

Thank you so much for your help!
