Hi @Alyssha, thanks for sharing this information. It looks like it may be a server configuration issue, where the user running your web server (often www-data on Apache systems) doesn’t have file permission access to the /var/cpanel/php/sessions/ea-php82 directory where your sessions are saved. This can happen with a new server that hasn’t been fully configured for PHP. Be sure to give your web server user read and write access to this directory, then try again.
