The most common cause is trying to use special characters, etc. greater than (>), less than (<), and ampersand (&) in the problem editor.

To resolve this issue, replace these characters on problem text with the HTML entities.

  • To enter >, type &gt;.
  • To enter <, type &lt;.
  • To enter &, type &amp;.
