Comments.Text: What version is the site running now? What does the web server error log mention? Did you upgrade from ``2.6.2791``?  ``2.6.2903`` is the the latest version.  Could be permissions but you'd need to check your web server's error log to find out what's causing the error. Craft shouldn't touch your images folder permissions during an update...

  Most likely you've got an Assets field inside of a Matrix field somewhere on your site and you're referencing `project-images/{slug}` in that field's upload location setting when it should be `project-images/{owner.slug}`.
  
  At some point, those settings were more loosely enforce, but now the error you're getting will be shown if it is incorrect.
