Trying to change from an existing theme – everything is broken. Everything.

So I have a website (www.ktbphotography.ca) that is running on a rather old theme called PhotoPro from Themeforest, and since I loved using Enfold on a new website I made, I was considering licensing another copy of Enfold for my old website. But after some research, I read that changing themes can be a bit tricky sometimes, so I decided to make a clone site first to see how well the themes transition from each other before spending money on a new theme.

Essentially, everything went wrong. I put a link in the private content and see for yourself. I think this might have something to do with different shortcodes, but seeing as how messed up it is, I have absolutely no idea what’s happened or whats wrong. At first I thought maybe my old theme just has coding that doesn’t take well to new themes, but I’ve tried various other free themes from WordPress, including their default Twenty Fourteen and Fifteen and they seem to transition fairly well. At least the general structure is there.

So I thought “Okay, maybe it’s just because it’s a fresh theme with nothing built on it”, so I imported a “Photography Demo” since it’s the closest to what the current website looks like, But still, the website looks royally screwed. So some insight into what happened and how to fix it would be much appreciated…
