I had my website up and running perfectly, yesterday I updated Grav and all plugins via Admin. And now I see this error above.

I've tried what's suggested on here https://learn.getgrav.org/16/troubleshooting/permissions
still nothing, except I'm now not able to edit files thru FTP.

Thing is everything was running smoothly until the last update.

The only thing I remember doing other than the update, was adding the suggested line in the admin section to CRONTAB... (I don't remember in which section it was suggested)

Does look like a permission issue, something wrong with cache/ folder that webserver is now not able to write to.

I got the same error after a update, then I fixed it by reset permissions:

# cd /var/www/html/cache
# chown www-data:www-data -R .

Have you moved the site between servers? As this one does not look like a bug but issue after copying dev site over into your server (bad permissions).

I'm using docker-grav and I ran gpm update as root.

[mahagr]

You should run CLI commands as the same user your web server is using (example is from Ubuntu):

sudo -u www-data bin/gpm update

[10-5]

Yes. And for docker-grav:

docker exec -u www-data -w /var/www/html grav bin/gpm update

chown www-data:www-data -R .

chown -R www-data: . should be enough
