I have also restored backups to the hosting but the connections are not showing up, why is this happening?

Hi, sorry for waiting. Most likely there are some issues with ids of those things services/locations/workers. Do you have any error inside browser console when you open connections page? Best regards, Nikola

I don't see any apparent errors on the connections page. I would appreciate a quick response, since we paid for it at the time, and all this should not fail.
Thank you.    

Sorry for waiting. If you have access to database on hosting you can check what is going on inside ea_connections table. Those rows should be there. If that table is empty then restore from backup was partial and you will have to add them manually. Best regards, Nikola

I already had to do it manually... what I would like to know is why this happens and how to avoid it.
