Page Builder missing from site
The most common cause of Page Builder missing from sites is that you have connected a custom domain but are still using the default "teamsnapsites" URL to log into your website dashboard.
Before mapping a custom domain, you would have wanted to log into your Website Builder site to access your Page Builder tools using the default domain:
Example URL sitename.teamsnapsites.com/wp-admin
Once you have a custom domain, you will need to log in at that custom domain in order to access your Page Builder tools:
Example URL customsitename.com/wp-admin
If you are logged in to Website Builder, but Page Builder isn't launching for you, try logging out, clearing your browser cache, and then log back in at your custom domain + /wp-admin/ and you should be good to go!
