The following information is directly from the phpBB3 Chmod Permissions KB article on phpbb.com. I found these to work as expected.

  • config.phpAll other files – 644
    • 666 before installation
    • 644 after installation
  • All other files – 644
  • All directories – 755
    • The files directory – 777
    • The cache directory – 777
    • The store directory – 777
    • The images/avatars/upload directory – 777

Modifying Permissions

Change all directory permissions in the specified path to 755

find /home/user1/ -type d -exec chmod 755 {} \;

Change all file permissions in the specified path to 644

find /home/user1/images/avatars/upload/ -type f -exec chmod 644 {} \;

Troubleshooting

  • If having any issues with avatars/attachments displaying make sure you reset the browser cache after making any permission changes.
  • I’ve found that cache/data_global.php sometimes needs 777 or some administrator actions fail.
