Hi Experts,

When I upload a css file to check it in the W3C validator it is successfully validated.  When I point the validator to my site (Joomla site) it fails with 2 errors:

20  Unknown error org.w3c.www.http.HttpInvalidValueException: Invalid content type.  
21  Parse Error //-->  

The site looks fine and the HTML successfully validates.

Any idea why this happens?  It there something in Joomla causing this?


Thanks,

HNM

Hi HelpNearMe,
First of all when you pass a URL to the W3 validation it validates the markup (HTML) not the CSS.

The error you are receiving doesn't have anything to do with either your html or css, actually it's from your server which seems not to return a Content-Type header.
The validator didn't even try to validate your code since it can't parse it hence the (Parse Error)

if your web hosting is linux based you can try to have your provider correct the server's .htaccess file to define a MIME type for HTML files or add it yourself if you have your own file.

There are many other possibilities depending on the situation, whether it was linux, IIS, re-write etc.., so you should troubleshoot your server's header (Content-Type) rather than looking for an error in your code or css.

Hope this helps

Hi remorina,

 W3C does validate CSS  http://jigsaw.w3.org/css-validator/

I'll look at the MIME & .htaccess file suggestion but does anyone else have comments?

Could this be related to Joomla?
