Data-wf-site and data-wf-page tags (part 2)

Regarding this post - I removed data-wf-site and data-wf-page tags from the html tag, however I get an error when loading all pages:

Oops! This page has improperly configured forms. Please contact your website administrator to fix this issue.

Looks like this is being triggered by Webflow JS. Is there a way to remove the tag and disable the message above? @PixelGeek gave original advice.

Thanks
