Incorrect data for “last attempt to log in”?

We use a user export plugin on our site for a closed member area.

Unfortunately, the data that WP Cerber passes on to the plugin is incorrect.
This means that many of our users have never logged in.
With the help of another plugin (Simple History), we can even see that this is not correct.

In WP Cerber we get the error message from the screenshot below.

What can I do to get correct data from WP Cerber?

I do not understand you. What data? WP Cerber doesn’t “pass” anything anywhere.

Last_Login
The “user export plugin” that we use has a new column since the installation of WP Cerber: “last login”. See screenshot.

The column shows the last login per member. Or it displays “never”.
And “never” is proven wrong in some cases. Says both “Simple History” and some of these people.

Does this explanation make it easier to understand?

Sorry, I’ve just realized that the screenshot of my first request was lost…

The export plugin you’re using relies on data that it’s not designed to export. The “last login” column is intended to be displayed on the Users page, not for exporting data.

Simply put, the plugin takes all the visible columns from the Users page and attempts to process them, even if the data in those columns isn’t exportable. This appears to be a bug or oversight in the plugin, as the developer should account for which columns can be reliably exported.

WP Cerber starts logging and displaying login events from the moment it’s activated. Any logins that happened before the plugin was installed aren’t recorded. That’s why you see “Never” for some users. It simply means there’s no login activity logged since the plugin was set up.

Unfortunately, a large number of these users with the “never” tag were only recently logged in.
We suspect that this has something to do with the reference to “Array” in the screenshot. Do you have any insights into this?

We have been using WP Cerber since 2022.

Yes, it looks like a bug. Please make sure that you’re using the last version of WP Cerber, you can enable automatic updates as well: https://wpcerber.com/automatic-updates-for-wp-cerber/

Thanks for your help, @Garry !
The plugin is always up to date in our WordPress.
Is there anything else we could do?

And can you please tell us what the “array” actually means?
Perhaps this will help us to find the error…

Any news on this?
We also see this “Array” Bug on the last login table.

It would be interesting to identify the root cause of this issue. However, it’s hard to determine what causes this based on a screenshot. Do you see this for any user, or is it an isolated issue?
