Hello there,

I manage a WordPress site using wpForo. I'm encountering a fatal error that occurs consistently when a new user registers and logs in for the first time, immediately after clicking the confirmation link in the account activation email.

The error is the following:

Fatal error: Uncaught TypeError: array_intersect(): Argument #1 ($array) must be of type array, null given in /wp-content/plugins/wpforo/includes/hooks.php:37
After refreshing the page, the error disappears and the user is properly logged in. However, this clearly disrupts the registration flow and causes confusion for new users.

Could you please let me know if this is a known issue, and whether a fix or recommended workaround is available?

Thanks in advance for your help.
