Hello how can i slove this ?

Mixed Content: The page at 'https://www.lannonce.eu/' was loaded over HTTPS, but requested an insecure stylesheet 'c'. This request has been blocked; the content must be served over HTTPS.

I find in header

//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css

i replace with this
http://maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css
and nothing change. where i have to look?

Please someone help


SOLUTION:
I have radius_search and in index also is

//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css

just change it to https://maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css

Best way is to use //, it is relative notation. On SSL page it is rewritten by https://, otherwise it is http://

My site is running full SSL just right now with no issues at all.
