Don’t worry, we will find the issue. But for that we need to know what is causing it. The URL you shared is not showing any errors that I can see. I see the plugin is running, but no error on the pages I’ve checked.
And the screenshot is not very helpful, as it doesn’t provide any information about which line of code is causing the fatal error. Could you please share your error log with us? If you cannot identify the lines you need to share, you can share the whole log using wetransfer or any other sharing service.
Could you also provide some more detail about where and when the error happens? I mean, is it happening on your Dashboard or public site? Does it happen on a particular screen or after you try to perform any action?
Please let us know so we can look into it.
