Magento

I solved this problem by adding the hostname of my store to /etc/hosts thus

This sorted the ‘This Url is not valid’ problem for me.

If this sounds a little crazy, it’s not as daft as it seems. It would appear Magento installer does a quick check to see the URL you enter is accessible and my fire wall was blocking packets coming back in from the same as source IP address. By specifying the local ping-back address (127.0.0.1) magento installer could verify the Url without going past the firewall - viola!!

I guess that was a rare case for me, but who knows it might help someone else along the way.

Just downloaded 1.1.3 Full release and I’m having the same problem.
I checked aforementioned Config.php file and it seems to have been patched.
So now I have no clue what to be looking for.
My setup :
- Linux debian etch
- PHP 5.2
- Apache 2.2 / mod_rewrite

Go into root modus in your shell, open up /etc/hosts in your editor and add:

127.0.0.1 sub.yourdomain.com

that worked for me.

I wanted to install magento on apache2 password protected dev.domain.ru, but magento said that url is invalid.

FIx was removing authorisation, installing magento, enabling authorisation again.
