If you can access the /validate URI, it will tell you the commands to fix the access rights issues.

Last time I saw this screen it was because the server storage was full :thinking:

If the rights are ok and you have free space, there are the more esoteric possibilities of max file handles reached or all inodes are used up.

storage was fine not full and no error, it turns out i need to change php-fpm user and group to librenms and everything works fine now.
