We have detected 2 major problems. You must fix them before continuing:
Mautic is unable to write your configuration file to the appropriate location. Please check your filesystem permissions to ensure the following path is writable: /var/www/html/config/local.php.
The directory must be writable. Change the permissions of the directory so that the web server can write into it.
We have detected some minor things that we recommend changing in order to have a better Mautic experience:
It is recommended to secure your installation with an SSL certificate (https). Starting February 2020 Google Chrome will stop sending third-party cookies in cross-site requests unless the cookies are secure. Tracking will stop working for Mautic instances running on HTTP. Use HTTPS.
