I have read several sites recommendations for WordPress file permissions. The standard recommendation is 755 for directories and 644 for files (or at least PHP files).

After making that change, I have spent the last two days correcting that error.

Specifically:

  • There are cache directories that need write permissions
  • If you update a plugin, write permissions are needed.
  • Autoupdate needs write permissions on many files
  • BackupBuddy needs…

You get the point.
