By default, FCK turns on the XHTML formatting option, so when some people change the full HTML file with visual editing, the head part may be changed to not resemble the human shape, and the workaround is as follows:
Open Include/fckeditor/fckconfig.js
Found it
Fckconfig.enablexhtml = true; Unsupported:do not a change.
Fckconfig.enablesourcexhtml = true; Unsupported:do not a change.
Switch
Fckconfig.enablexhtml = false; Unsupported:do not a change.
Fckconfig.enablesourcexhtml = false; Unsupported:do not a change.
Then delete your browser's temporary files, refresh the current page, you will find, no longer be FCK spoof
