Multiple situations

Hi! I have a couple of problems with Robolist Lite’s theme.

1. First of all, the Background Image doesn’t appear on the mobile…The preview appears without any problem, but when you check in a real mobile just appears a grey square.
2. In the listing, the space for the address doesn′t adapt to the full information.
3. Finally, in contact form 7 “to contact the business” isn’t working some of the information is missing.
4. I try to contact directly with the provider through their page and start a ticket but is impossible to register, just nothing happen…no email confirmation or a message.

I appreciate all your help in advance.
Best Regards
