Failed to execute 'insertAdjacentHTML' on 'Element': The provided markup is invalid XML, and therefore cannot be inserted into an XML

Who can help me with this error? I ‘started from scratch’ to build a new form. After 1 question I already receive this error. It was working fine a few months ago…

@Kobotools please support

The issue is related to:

  • online/offline data collection

because when only ‘online only (multiple data submissions)’ is selected, then it does work

But that option is not ideal for work in the field…

Welcome to the community, @operations_green_ear! A quick question. Have you validated your XLSForm through this online validator? If no, would you mind validating it once? Besides, could you also let us know the browser you are using for this (that returned an error message)?

I haven’t created an XLSForm, I have created all the questions straight onto the Koboplatform from scratch

Chrome is the used browser

You could always check your XLSForm by downloading them and validating them against the online validator.
