character „<“ is the first character of a delimiter but occurred as data
Fehler: </ br>
- You tried to include the „<“ character in your page: you should escape it as „<“
- You used an unescaped ampersand „&“: this may be valid in some contexts, but it is recommended to use „&“, which is always safe.
- Another possibility is that you forgot to close quotes in a previous tag.
