discarding unexpected <...>
Cause:
A opening or closing tag was found, but is currently not expected.
- Opening tag: the expected tag is not at this location.
- Closing tag: the tag is not opened. (This can be caused by an earlier error.)
Example:
 | <b>abc</b></b> |
 | <b>abc</b> |
Solution:
For a closing tag, remove the closing tag or add the missing opening tag.
