Help for deployment

Hello everyone,
I need some help.
I’ve designed an XLsForm that I’m trying to deploy, and I’m getting this error message.
If this problem persists, please contact help@kobotoolbox.org
Server Error (500)
I don’t know what’s causing the error.

@KAMBOU, would you mind validating your XLSForm through this online validator? The online validator should help you identify syntax issues if any present.
