Moodle Login Page is not shown in different language using Firefox

When using Firefox, apparently your moodle login page is still showing some English phrase even though you already force the site to use other international language.

To fix it, just copy Moodle.php from that international language, usually on the moodledata/lang/ folder to the moodle/lang/en_utf8 folder.

This will override the English language.

First, you need to create a transparent background images. Then the picture is set, you need to set the color - mode to indexed.
