keep getting this message, any ideas please.
I've read the documentation for Grav (troubleshooting) but am unsure about using the following script:
!/bin/sh
chown joeblow:staff .
chown -R joeblow:staff *
find . -type f | xargs chmod 664
find ./bin -type f | xargs chmod 775
find . -type d | xargs chmod 775
find . -type d | xargs chmod +s
