Some fields in sp-form-global-options.php with language conditional tag “sp_text” are not getting translated while they are present in the .po and .mo file. For example these lines:
$out.= sp_text('On this panel, you may set your Global Options preferences.');
$tout.= '<p class="spProfileLabel">'.sp_text('Hide Online Status').':</p>';
$out.= '<input type="submit" class="spSubmit" name="formsubmit" value="'.sp_text('Update Global Options').'" />';
This should be changed in the core I think.
