When ever the web page is loaded i am getting warning in the debugger as
Resource interpreted as stylesheet but transferred with MIME type text/plain.
I am getting the above warning when the browser requests for js, css, gif and png files.
Any idea how to resolve this warning
Well the error message says it all.
Your webserver sends a wrong/missing Content-Type HTTP Header.
Use HTTP Header Check and enter the url of your js/css/gif/png and check what Content-Type header the server sends (I guess none at all or text/plain).
Then fix your server to send the correct mime type along or contact your server administrator.
The correct Content-Type values should be
text/css
-> for .css files
image/gif
-> for .gif files
image/jpeg
-> for .jpg/.jpeg files
application/javascript
-> for .js files
image/png
-> for .png files
Consider yourself lucky ;). Now it is just a warning in Chrome, in earlier versions of Chrome when a wrong/missing Content-Type Header was set/sent the e.g. CSS wasn't applied at all.
