How can I resolve invalid settings and disallowed attributes in tags?

The “heading” setting is invalid. Attribute “data-mce-fragment=‘1’” is not allowed in tag “” and attribute “data-mce-fragment=‘1’” is not allowed in tag “” and setting “subtext” is invalid. All top-level nodes must be ‘

’ ‘

    ’, ‘
      ’ or ‘

      ’ - ‘

      ’ tags

It seems that the “heading” setting is invalid, which could mean that you are using a tag that is not allowed, or you are using an attribute that is not allowed in a specific tag. The error message also indicates that the “subtext” setting is invalid and that all top-level nodes must be either “

”, “

    ”, “
      ”, or “

      ” - “

      ” tags.

      To resolve this issue, you will need to review the formatting of the content you are trying to add and ensure that it conforms to the standards specified by the platform or application you are using. Specifically, you may need to remove any invalid tags or attributes and ensure that your content is structured correctly using the allowed tags.

Hi @uygargoyunc

The attribute “data-mce-fragment” is not a valid attribute for the and tag in HTML. This attribute is usually added automatically by certain text editors, such as the TinyMCE editor, to mark content that has been copied and pasted from a rich text editor.

If you want to apply styling to text using the tag, you can simply enclose the text you want to style within the opening and closing tags.

Hope this can help you.

Kind regards,

I have a similar problem
