Error trying to edit with Visual Composer once created

I found this plug in and started to use it yesterday, and it’s exactly what I was looking for. I began by editing some of my pages to make them more mobile friendly, and was able to jump back and forth between them to ensure font styles/sized etc were all the same.

I have gone to begin working on the rest of the pages today, and needed to pull up the previous mobile versions so that I again could copy the formatting over. However, when I click the edit the mobile versions with my plug in, Visual Composer, the page will not load. I have tried clearing my cache and browsing history, turning my laptop off and on again, but it’s still not loading.

Also, yesterday when I began to create the mobile version, I started with a completely blank page which I had to copy over from the desktop version. However, now when I click to create a mobile site, it copies the data over. This isn’t necessary a problem, because it saves me having to manually input everything again, but I am curious as to why that will have happened.

I hope someone can help solve my issues!

Thank you
