TYPO3 Exception 1460629247

TYPO3 8.7.1

Error: No valid handlers found for type: javascript

Happens after saving in CKEditor.

You may have received this error, because you are trying to save a non-compliant link in CKEditor. Usually CKEditor will eliminate (remove) such links - but in combination with extraAllowedContent it might happen that the link passes the filter.

For example, this would cause the error above:

href="/impressum/"
Copied!

Valid links would be:

href="t3://page?uid=175"
href="https://typo3.org"
Copied!
