Technote Details :: I get an Unknown Content-Type error when accessing a KTML module
Issue
When accessing one of the KTML modules I get an error message:
KTML has received a response with an unknown \"Content-Type\" header in module module_name, method method_name.
The Content-Type response header is: response
Reason
This happens because the web server has returned an invalid charset header for the AJAX request sent by the KTML module.
Solution
When this error occurs KTML automatically transforms the request result into a ISO-8859-1. If you are not using incompatible characters you will not notice any problems. If, however you have specific encodings, it will be lost.
To completely solve this problem you must edit the web server configuration and instruct it to pass a default charset different than None. Instructions on how to change this specific setting can be found in the web server's manual.
