### Additional Settings that may need to be enabled for some servers

### Uncomment the commands by removing the # sign in front of it.

### If you get an "Internal Server Error 500" after enabling any of the following settings, restore the # as this means your host doesn't allow that.

# 1. If your cart only allows you to add one item at a time, it is possible register_globals is on. This may work to disable it:

# php_flag register_globals off

# 2. If your cart has magic quotes enabled, This may work to disable it:

# php_flag magic_quotes_gpc Off

# 3. Set max upload file size. Most hosts will limit this and not allow it to be overridden but you can try

# php_value upload_max_filesize 999M

# 4. set max post size. uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields

# php_value post_max_size 999M

# 5. set max time script can take. uncomment this line if you have a lot of product options or are getting errors where forms are not saving all fields

# php_value max_execution_time 200

In attachment , there is the directory structure
Please guide me how can i resolve it.

My problem has been resolved. the problem was from the server end. I called my hosting provider and they resolved it.

A setting in Apache needs to be changed in httpd.conf
<Directory "/var/www/html">
#
# AllowOverride controls what directives may be placed in .htaccess files.
#
AllowOverride None
</Directory>

change to AllowOverride All
