I was getting
CONNECT ERROR: Failed to create directory:www.../shop/./app/code/core/Mage/Install/Controller/Router
and after that the shop admin and shop were not reachable.
What I had to do was delete folder
and load the connect manager again. Start installation. After that the shop came back up with 126.96.36.199
Maybe this helps other folks.
Go to Solution.
Thanks for the post!
