HTML Guide for st_url

Attribute “st_url” not allowed on element “span” at this point.

st_url
span
not allowed

The attribute st_url is not allowed on <span> elements.

This issue is commonly caused by an old integration of ShareThis via Drupal or other CMS - the old code used invalid attributes like displayText, st_url and st_title which were later changed to HTML5 custom data attributes.
