Error uploading a survey

I have created a survey on Kobo and when trying to copy the link to collect data I have received this error message:

"Error occured during the loading of this form. We do not recommend you use this form for data entry until this is resolved.

Please contact with the link to this page and the error message below:

Failed to execute ‘insertAdjacentHTML’ on ‘Element’: The provided markup is invalid XML, and therefore cannot be inserted into an XML document." I have contacted the customer support and they asked me to post the question here. All help is much appreciated!

Just a note that this is the survey link in case it helps provide some clarity: Enketo Express for KoboToolbox

@engelsm, maybe try validating your XLSForm through this online validator to see if there are any syntax issues that are affecting the deployment.

Hi thank you for your response. I used the validator and it worked well on the preview I then tried to upload the very same XLS file I used on the validator onto a new kobo project and again I received the same error. Any other ideas?

To add on this I realise now that the survey works fine when I use safari internet browser it seems to only be an issue for google chrome and I have tried on two different computers. Is there any way I can fix this because many respondents will be using google chrome!
