Many of the result tables in DirectAdmin are hardcoded, meaning the text is set in the DirectAdmin binary and cannot be changed.
A trick to translate these hardcoded values would be as follows.
Find the html skin file which has the hardcoded token. Lets say it contains
|TABLE_TOKEN|
Edit the file, to change that value to the following:
|$/usr/local/bin/php
<?php
$data = <<<END
|TABLE_TOKEN|
END;
$data = str_replace("englishtext", "newtext", $data);
$data = str_replace("englishtext2", "newtext2", $data);
echo $data;
?>
DONE|
Where englishtext is what's currently hardcoded, and newtext is what you'd like it to be translated to. You can add as many str_replace commands as you'd like, but note that this isn't very efficient, so too many of these commands could slow things down.
