I have two magento websites in domain and subdomain like test.com and test.test.com.
In Domain website and admin panel works fine. But In Subdomain website the customer registration not done.After submit it only reload the registration page. I also enable log and check the log file but there is no error.
Also In Subdomain admin panel.I can login and view the admin panel dashboard.I can also view pages and blocks. But I can't create new page and update the page.After click on save it simply reload the page.
I use nginx server.I didn't change nginx server configuration after creating subdomain.
Please give me suggestion.I face this problem since last week.
