I don't know what this prestashop thing is but I couldn't find a better option. My visual composer is not allowing any updates I make to apply. I can't delete any items and if I add an item and hit "apply" the page refreshes to the default layout and all the changes I make are lost.

I don't know how these will help you understand any better. I purchased a theme from you called "Food Store". The theme comes with "Visual Composer" by WP Bakery. I use visual composer as a page builder. However, it doesn't work. Non of the changes I make are saved when I hit the "Update" button.

If we can't get this to work I will whole heartily demand a full refund because it will likely result in me losing a client.

This may better illustrate what the problem is.

I know you guys are hard at work on this one but I've got an update for you. I installed the theme and plugins onto another website I manage that's under a different host provider. It seemed to work flawlessly. I reinstalled the theme and plugins on the original website but it has not seemed to make any difference at all. 

Its host is GoDaddy using the managed wordpress hosting option.

This has been the strangest problem I have run into in a while. I switched to Chrome, before using your plugin, and it let me delete content and update those changes but it would not let me add any content. 

I installed your plugin and it seems like everything is working on FireFox (which I prefer) but no change on Chrome (which I'm okay with). Long story short, make sure your clients aren't hosting with GoDaddy. They are a joke and you'd be better off just using Wix or Square Space then having to deal with their unprofessional setup. 

Thank you very much Jamie for helping me out on this one.
