Silverstripe Version:3.7 to 4.5.2

Question:dev/build?flush=1 gives No URL rule was matched

I am trying to upgrade my silverstripe site from 3.7 to 4.5. I managed to go through all the steps till 8 of the upgrade process. Now when i try to do <>/dev/build/?flush=1 i get No URL rule was matched. Actually visiting anything of the site gives me “No URL rule was matched”

I some one point me in the right direction as in where and what to look for please

I have routes.yml and its working fine in 3.7 but not in 4.5

Cheers

Are you trying from a browser or in the command line?

If the browser isn’t working, it might be worth trying to run via the command line. (https://docs.silverstripe.org/en/4/developer_guides/cli/)

If the command line works, then check the web server config - are you using the public directory, does it contain the right files, is the server set to use it as the document root, etc.

thanks for the reply. Yep i tried from both end and the result is the same. “No URL rule was matched”. I check the settings and they seam to be in place as how they should be. Again i used the upgrade tool kit.
