How can I fix this problem?, when i try to share my link on facebook this appears…
I don’t know?
Facebook hates free hosting for some reason. Unfortunately, there doesn’t seem to be any way to fix this when using free subdomains, but you can post your website freely when you use your own domain name.
That ‘reason’ would be because of scams and spammers.
You can always try use a URL forwarder, but these are not always guarantee to work with Facebook, one that will work is http://take.us.to/
