Judging based on the code you added, I see 1 quotation mark, it should be 2 if you plan to use them in the code. Open and Close. You don’t necessarily have to use them if you don’t want to, but if you do just make sure there’s 2.
This should work –
background-image: url(https://demo.appfinite.com/demo/wp-content/themes/oasis-old/config/import/images/homepage-bg-2.jpg);
Both background and background-image work for me. If you haven’t tried “background-image” see if that helps.
If it’s still not showing up, double check that the link to your image is working.
I had to setup a separate/local server and install this version of the theme since I didn’t have it installed anywhere (I just have the New version installed). But once I tested the CSS it works fine on my end.
Let me know if that helps!
