Updated Avada. Now my shortcodes are showing. Can anyone help me?

We recently updated our Avada theme from 4.0.3 to 5.0.5, and encountered some problems with our website. When I updated the Fusion Core plug-in to 3.0 and installed the new Fusion Builder plug-in, most of our website’s shortcodes revealed themselves. I was able to fix this by uninstalling the Fusion Builder plug-in and reverting to an older version of Fusion Core, but doing so killed some pages tucked away inside our website’s main header.

When both Fusion Core and Fusion Builder are updated and installed, the dead pages come back to life. But the shortcode is visible and distorts the whole website, so the bigger problem persists.

Here is a visual example of what I mean: https://postimg.org/image/vyq5868sp/

I’ve done some digging and it sounds like any of these below solutions may do the trick. I am hesitant to do anything major without first speaking with someone more experienced, and I’d appreciate any advice the support team/evanto community is able to provide.

Possibility 1

I can manually convert shortcodes from Avada 4.0.3 to Avada 5.0 through the System Status interface. My gut tells me this is the solution. It sounds very similar to a problem another user named Zarakoa expereinced, evidenced here: https://themeforest.net/item/avada-responsive-multipurpose-theme/2833226/comments?page=1188

Possibility 2

I have several backups from before the Avada 5.0.5 update was installed. Would deleting the Avada theme and reinstalling the older version from a backup fix the problem? If this is true, I’d probably need to also reinstall the earlier Fusion Core and discard the new Fusion Builder plug-in.

Possibility 3

Maybe it’s a memory limitation? By default, we are allocating 40 MB to our website. 40 MB has been our standard for a while, so I’m not sure that’s the source of our problem.

We also updated our WordPress site to version 4.7 yesterday, but I do not think that has any impact on the issues above.

Thank you!
