Buttons not showing on any broswer?

First off, that looks great! Secondly, your buttons actually are showing for people, so it’s likely that your own device or connection is filtering out social buttons.

Try another device and Internet connection to pinpoint the cause. Some anti-virus application (such as Avast) have an optional “feature” to filter out social buttons on websites. Less often, the cause is a similar optional feature that’s enabled on a router.
