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.
- 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.
