I flushed my cache and it’s still the same.. It’s weird you didn’t see any problem, did you navigate on the site ?
Also, I’m not using caching plugin.
And it seems right now that even my homepage is not displaying the favicon, I only see it in when I’m on the WP dashboard.
Hmm, that’s core WP functionality, not sure why it wouldn’t work.
The other option is to upload your favicon.ico file into the root directory of your website via FTP or file manager. This will apply the favicon to your entire site automatically.
When you say “upload your favicon.ico file into the root directory of your website via FTP or file manager.”
Do I only have to put my file in the main folder ? If so, I tried it but it didn’t work.
(I generated my favicon.ico with this http://www.favicon.cc/).
That’s right, it would go in the same directory as your wp-admin, wp-includes and wp-content folders.
As long as it’s named favicon.ico, it will work. You will need to clear your browser cache and even wait a couple hours for it to show up as favicons are heavily cached.
