Hi.
Looking at your code, the code inside main wrapper is simply missing. Not hidden, missing. If you’ve done any customizations to the code, roll it back. Beyond that, I can’t really recommend anything. This is certainly not a ‘feature’ of the plugin 🙂
Try doing the default WordPress troubleshooting; enable one of the default WordPress themes, disable all other plugins and then enable them again one by one to see where the issue is coming from.
Cheers.
