When a user tries to delete their own account via the frontend profile page (/participant/username/?wpfaction=user_delete&_wpfnonce=XXX), it always fails on the first attempt with:

"User delete error: missing argument."

The server returns a 302 redirect to the members page, but the error is set. Clicking delete a second time works and the account is removed.

We confirmed via browser DevTools that the error is rendered server-side in the HTML. We tested flushing permalinks, deactivating all other plugins, and different user accounts — the issue persists. Custom URL slugs are configured (member → participant, members → participants).

It seems like wpForo does not correctly resolve the user ID from the profile URL on the first delete request. Could this be related to custom slug configuration or a PHP 8.3 compatibility issue?

Any help appreciated. Happy to provide more details.

wpForo 2.4.17 | WordPress 6.9.4 | PHP 8.3

Hi,

Please note that wpForo uses WordPress functions for deleting users. In other words, user deletion is managed by WordPress, so this issue should not be related to the wpForo plugin.

However, I’ll ask the developers to check this one more time. I’ll update this topic soon.

In case you want to say thank you 😊

We'd really appreciate and be thankful if you leave a good review on plugin page. This is the best way to say thank you to this project and support team.
