Title: Custom HTML: data-attributes disappeared Last modified: July 31, 2026 --- # Custom HTML: data-attributes disappeared * [lerev](https://wordpress.org/support/users/lerev/) * (@lerev) * [1 week, 2 days ago](https://wordpress.org/support/topic/custom-html-data-attributes-disappeared/) * Found a bug. If use the “data-attribute” in the “Custom HTML” element in a plugin version above 2.1.7+, it will be erased. For example, it changes “” to “”.
