Thank you for purchasing the theme.
For error 1 – please go to Admin – Theme Options – Advanced Search and select 1 feature from Features and Amenities list there. You have none selected and that is the cause of the error
Or turn that option to NOT display, from the same page.
For item 2 – you have to enable social login for each option from Theme Options – Social & Contact (look down, last 3 options). Help http://help.wpresidence.net/#!/social
Then you have to set-up 2 API, one for Facebook and 1 for Google.
Google login –
