My directory layout is like so:

index.php

2nd time I’ve run into this. Somebody needs to edit the upgrade guide to point out that we need to make an application/logs directory and update our application/config.php. Also, other updates occurred in the application folder that went unmentioned in the guide.

Is there a reason why you can’t add it yourself and issue a pull request on github so it gets added?  Otherwise, it probably won’t unless someone happens to read your post and decide to take it upon themselves, which isn’t too likely.

For me on windows 7 pro using Internet Information Services 7.5,

I unsuccessfully added the IIS_IUSR group with full permission, no success.

But adding my local account’s IUSR user account with full permission (write would probably do)  allowed codeigniter to write to the log directory
