I faced this issue when i tried to create a new user on Ubuntu server, new user was given the Bourne shell rather than the Bash shell, this is a basic shell located in /bin/sh, and it looks boring, you won’t be able to use auto-completion with such shell. in this article, i will show you how to change default shell of an unix user.
When I changed the URI to access to my dashboard, when I logged in again, there was a 404 error on the admin dashboard. It seems is something related to permissions and can be easily solved executing the following commands:
find . -type d -exec chmod 755 {} ;
find . -type f -exec chmod 644 {} ;
chmod o+w var media -R
If this doesn’t work, maybe the login form is not redirecting correctly. In that case we need to change the action url in the app/design/adminhtml/default/default/template/login.phtml file. Look for the «form» start tag:
<form method="post" action="" id="loginForm">
Change it to:
<form method="post" action="<?php echo $this->getUrl('adminhtml') ?>" id="loginForm">
that’s it, you have you familiar dashboard back 😀
