Images not showing on Multisite

The images are not showing.

So I’ve read the support forum and I’ve narrowed my issue down to the fact that I’m using multisite version (non-domain) and the variable “$rps_img_src_path” can’t properly get the url (the html output doesn’t even show a link tag). Or that’s at least what I’m assuming at this point.

Because I’m not good with php, I was wondering if you could tell me how the variable should look like on a multisite.
