To give permissions to you SuiteCRM 8, you will have to go to the console of the server where the domain is hosted and access the folder where the CRM files are. Then execute this commads:
find . -type d -not -perm 2775 -exec chmod 2775 {} ;
find . -type f -not -perm 0664 -exec chmod 0664 {} ;
find . ! -user <apache_user> -exec chown <apache_user>:<apache_group>{} ;
chmod +x bin/console
