If you cannot share your website link on Facebook, it could mean that your domain is blocked by Facebook. This can happen on several reasons but most of the time, it is blocked due to spamming with the link on Facebook. It means that the link has been shared on Facebook in an unusual manner. Facebook does not tolerate any type of spamming. If this happens for your website, you can check the reason for your ULR block from here: https://developers.facebook.com/tools/debug/ and take actions according to it.
