If you are getting a similar error message in you application:
session_start(): Failed to read session data: files (path: /var/cpanel/php/sessions/ea-php81)
It means there is an error with the PHP configuration or webserver file permissions, so you will need to contact your host support to fixed. However, there are a couple of alternative solutions that can work.
First Option:
Go to hosting panel (cPanel, Plesk u other) and change the PHP version of your site. As each PHP version has its own configuration, this simple change can fix the issue.
Second Option:
Add this code to install.php and index.php
ini_set('session.save_path', __DIR__ . '/sessions');
And create new folder named “sessions” on the same folder in the app.
And that’s it!
