Trumbowyg-editor not accept language code: id

trumbowyg-editor not accept language code:id , When I add Indonesian language and select the language in edit, the edit box and the whole form are hidden. Please fix this problem.

Is this related to an addon only?

@tim yes, related to this addon only. There was a bug in the addon i created.
use file below (admin/intro.app/intro.inc.php)

there was this line in the addon:

<input id="id" type="hidden" value="<?php echo $id; ?>" />

Indonesion has #id in url, so stupid mistake. It did put the whole form on display none

ok

Which addon? I didn't see this topic connected to an addon. @off try editing your initial post and connect this topic to the addon of concern.

indeed, topic should be connected to this addon: https://www.litecart.net/en/addons/770/intro-frontpage

Thank you jack, it's now connected. 👍
