Hello, first of all thank you very much for your help ... I have installed wordpress together with xenforo and the xpress plugin, the free version that allows you to log in on one system and another. Wordpress is the latest version 5.5.1 and xenforo version v2.2.1 but it is not working for me.
When I login from wordpress with a xenforo user, the log throws me errors:
mod_fcgid: stderr: PHP Fatal error: Uncaught Error: Call to a member function exists () on string in /var/www/vhosts/adolphesax.com/nuevaweb.adolphesax.com/wp-includes/user.php:1385, referer : https://nuevaweb.adolphesax.com/wp-login.php
If I login from xenforo with a wordpress user it does not give an error but indicates that the user does not exist.
The Wordpress installation is:
La web hecha por y para los saxofonistas.Saxofón: Toda la información, eventos, streaming, conciertos, videos, foro, artículos, tesis, reviews. Recursos educativos y pedagógicos.
Forum software by XenForo
Do you know what the problem could be? Do I need the licensed version for it to work? In principle, I only needed to be able to login from wordpress or from xenforo.
As indicated in the plugin that works it would be good for me but it is not working:
Authenticate with WordPress
If enabled, when no XenForo user is found for the given login credentials, XPress Forum User Bridge attempts to authenticate the user against your WordPress installation. If a WordPress user is found, and a XenForo user for its email address exists, the XenForo user's password will be updated, otherwise a new XenForo user will be created.
