Not able to login user and not able to add product to cart in multistore Magento 1.9

[mahen_nag]

I've been searching all over to find a solution to our issue. We are running a magento 1.9.2.2 with multiple magento websites as subdomain:
website1.domain.com
website2.domain.com
etc..
Each website has a store view.

Issue: I could not add products to the cart nor the login user in the default website (domain.com) as well as in subdomain website, When i i have added product in cart then does not work. The message: The cart is empty. When i login using proper user details then just riderct page on same page.

I have used ssl for my website.

Checked:
- system.log file (no error as far as I can tell)
- cookies are set (tried all kinds of configurations), currently life set to 3600 (tested 86400), but tried also with setting various cookie domains, -> no effect

My last cookies setting is :

Configuration Scope: For Default Config

Unsecure:
Base Url : https://www.domain.com/

Secure:
Base Url : https://www.domain.com/

Cookie Lifetime : 3600
Cookie Path : /
Cookie Domain : www.domain.com
Use HTTP Only : Yes
Cookie Restriction Mode : No

Configuration Scope: For Store View

Unsecure:
Base Url : https://www.subdomain.domain.com/

Secure:
Base Url : https://www.subdomain.domain.com/

Cookie Lifetime : 3600
Cookie Path : www.subdomain.domain.com
Cookie Domain : www.subdomain.domain.com
Use HTTP Only : Yes

- prices set per website
- products released for all websites/stores

Hi @mahen_nag,

Update the following settings at global level only, not at website level. At website level select use default. 

Cookie Lifetime : 3600
Cookie Path : /
Cookie Domain : 
Use HTTP Only : No
Cookie Restriction Mode : No 

Also make sure that you have full write permission to var/ folder. 

sudo chmod -R 0777 var/

Also check once in app/etc/local.xml , session save config. 

I hope it will help you!
