Worst Nightmare

We use kadence for two different domains. One domain has had minimal issue, the 2nd domain has had issues since day 3. During the early days after purchasing the license, the support was great. Now after 6 months support seem not to exist. Kadence sent a update, the 2nd domain apparently didn’t update with all files, this is the second time with the same issue. I email them and they said just reload the theme, the problem is we can’t even get in to the shell to access and reload. We only get corruption message
example:

Not the best experience.
