Have you enabled 2FA or reCAPTCHA for any accounts outside of the user page, such as your admin account directly from **Wordfence > Login Security**? * Also are you using a fresh installation of Wordfence, or have you been using it for longer?

Background: Wordfence had been working perfectly. A while back I transitioned to a multi-site installation with plans for more than one site on the server, however, decided not to do that so removed multi-site. The site is running fine with no problems after downgrade to single site. Note sure that this problem is related to that or not.The get_current_site() makes me think that Wordfence still thinks this is a multi-site install. What might the fix be? * BTW, I’ve tried uninstalling and reinstalling the Wordfence plugin, but that hasn’t resovled the issue. * PHP Version: **8.3.0** WordPress Version: **6.4.2**WordPress Language Code: ** en_US** - This reply was modified 2 years, 4 months ago by [kognetiks](https://wordpress.org/support/users/kognetiks/). - This reply was modified 2 years, 4 months ago by [kognetiks](https://wordpress.org/support/users/kognetiks/). * [kognetiks](https://wordpress.org/support/users/kognetiks/) * (@kognetiks) * [2 years, 4 months ago](https://wordpress.org/support/topic/fatal-error-php8-2/#post-17336692) * Line 128 refers to             $network_id = get_current_site()->id; * Reverting from multi-site to single-site might be the root cuase. * How do we get this fixed? * I just deleted the wordfence_ls_role_sync_cron which might help/hurt? * Thread Starter [paulroberts](https://wordpress.org/support/users/paulroberts/) * (@paulroberts) * [2 years, 4 months ago](https://wordpress.org/support/topic/fatal-error-php8-2/#post-17338942) * it is multi site install * >Have you enabled 2FA or reCAPTCHA * Don’t think so, I have had to disable wordfence as users can’t log in - This reply was modified 2 years, 4 months ago by [paulroberts](https://wordpress.org/support/users/paulroberts/). * [kognetiks](https://wordpress.org/support/users/kognetiks/) * (@kognetiks) * [2 years, 4 months ago](https://wordpress.org/support/topic/fatal-error-php8-2/#post-17339537) * Deleting the wordfence_ls_role_sync_cron cron job seems to have resolved the issue.
