Post request not working Drupal and Ubuntu 14.04

In my ubuntu 14.04 OS machine for drupal 7 login not working, may be it is not only login but all post request not working here. For the same filesystem and codebase it works fine in windows 7 machine.

Here is my apache server configuration:

<VirtualHost *:80>

ServerName somedomain.local

DocumentRoot "/home/mycompany/Development/Projects/Drupal/cbb"

<Directory "/home/mycompany/Development/Projects/Drupal/cbb/">

   Options Indexes FollowSymLinks

   AllowOverride All

   Require all granted    

</Directory>

</VirtualHost>

for above configuration when i try to submit data for login it showing.. "NetworkError: 404 Not Found - http://somedomain.local/user".

#UPDATE:

I just find out that login not working only from www.domainname.local/user path but if this login form in homepage sidebar it works fine, for all of drupal sire in ubuntu machine. With this no error message also not display.

I am in trouble for two of my drupal site in Ubuntu machine. Any help will be appreciated.

Solution

Check if .htaccess file present in drupal root directory.
Check if you've added your domain to /etc/hosts file
```
127.0.0.1 domain.name
```
Domains with 'www' and without it are totally different. Add both to /etc/hosts and to apache's config file to avoid problems.
Clear cache to avoid previous domain name which could be stored in cache.
```
drush cc all
```
If you've just added new site to apache's configuration be sure to run:
```
sudo service apache2 graceful
```
