Hello, Chen.
Unfortunately we don’t know why FCKeditor is not working. Was it running under UltiDev Cassini in
debug mode? If something is not rendering correctly, please double-check the URL paths.
Fiddler Tool is a great HTTP interceptor that will quickly show which requests failed and give you plenty of information about why it’s happening.
Please let us know if were able to resolve the issue.
Best regards,
UltiDev Team.
