Windows XP IIS installation
Silverstripe 2.3.3

localhost/mysitename/?flush=1
works just fine
localhost/mysitename/
pulls up my site and all of its modifications just fine

localhost/mysitename/build?flush=1
localhost/mysitename/db/build?flush=1
localhost/mysitename/dev/build?flush=1

And just about all permutations of these fail with page not found
I cannot seem to find the way to rebuild my database and therefore cannot make any changes to it
I have been through most if not all of the forum notes with similar issues and none of the advice works on my installation
Help Appreciated!

Just solved my problem.
I hope this helps someone else

http://localhost/mysitename/index.php/db/build?flush=1

Without the index.php it fails
With the index.php it works

This did just help me,

and to add - if you're just following the tutorial (as its's written as of 5/2012,) this link might help. I'm using wamp. It looks like the above link will get you where you need, with one extra step now that it's dev/build

http://localhost/silverstripe/index.php/dev/build?flush=1

Thanks again

I've just had the same problem (with the same fix) while upgrading from 3.0.5 to 3.1.4, on my local machine which uses wamp.

Using mysite/admin/dev/build/ - a blank page is displayed which says simply: Not found
Using mysite/index.php/admin/dev/build/ - works as intended

mod_rewrite is working fine, I can access /admin and the public site pages.

Ed

Do dev/build without admin
