My apologies… Actually, I just carefully went through the zip file again that I downloaded from Mojo Themes on March 14th and it does appear that this is version 1.04. I had to dig a bit deep but I found files from Feb. 2015. Therefore the primary item from my post above is resolved.
I still do have the question regarding whether there is defensive code in the Skyline theme to prevent SQL injection on pages such as contact forms. If not, I’ll have to do a bit of research with regard to this. Being WordPress in general seems to be a primary target for hackers currently, I want to be sure the site is as secure as possible before I bring it on line again.
Any/all guidance appreciated!
