OpenSP: Character ... is the first character of a delimiter but occurred as data

Cause:

This message may appear in several cases:

  • You tried to include the "<" character in your page: you should escape it as "&lt;"
  • You used an unescaped ampersand "&": this may be valid in some contexts, but it is recommended to use "&amp;", which is always safe.
  • Another possibility is that you forgot to close quotes in a previous tag.

Example:

Bad<p>The first character of an HTML element is <</p>
Good<p>The first character of an HTML element is &lt;</p>

Solution:

Replace the character with a proper Character Entity.
