![The image shows an error message indicating that a site may not work properly, caused by a plugin named 'discourse-whois-online,' and is visible only to site administrators.

On 3.4.0.beta4-dev, and have been updating dilligently. Any idea where I should look for trouble? ---

Hey Geoffrey, Is the plugin up to date? The latest version is: ![image](https://global.discourse-cdn.com/meta/original/4X/7/2/3/723cf4f611c18297708a1a51f57a9f1e082b3200.png) ---

Yup! Looks like it: ![The image shows a "Who's Online" feature from a Discord, which displays a list of online users and their usernames, with an option to learn more about it and an update button labeled "Up to date."

Do you see any error in the browser’s console? I can’t reproduce it on a local dev and production instance. 🤔 ---

Good idea! I’ll take a look next time I see it. It seems to happen sporadically. I looked at the backend logs and nothing jumped out at me… As a suggestion, given that this message is only shown to administrators, it might be helpful if it provided more details about the problem, assuming that whatever is generating it in fact has more details. It’s already taking up a fair bit of screen real estate for a “something’s wrong” message. ---

I can’t reproduce on a clean production instance, but I do see an error on a dev instance: ![The image shows an error message indicating an uncaught in-prostraint revaluation failure, attributed to the direct use of 'et' on a pre-defined object, in an application called 'DiscourseTopic', with a detailed stack trace detailing the locations of the error in the code.
