2. If you wanty to keep it, then you may follow this:

• By registering an application at https://dev.twitter.com/apps

• Then open SP Tweet module (in edit mode) and fill all the data.

If you want to remove twitter, then you have to delete or disable addon with twitter or tweet name from Page where you see it.

Just:

• In Module Manager find module with "twitter" or "tweeter" name and disable - if any

• In SP Page Builder admin area - on list of pages find "Home" and DELETE addon with "twitter" name inside

Hope it helps!

Best Regards
