If you don’t want to enable the user registration please use predefined accounts to login. And let me test if the problem really not exist.
Thank you

hi
thank you for your reply,
the demo is installed from the beginning, the problem is when I’m logged as an administrator or as a normal user is that when I want to post an ad an click on the button it redirect me to login page even when I’m logged in. and also when I enter without login and click on the button post your ad i’m send to the login page which is normal but when I logged and click another time on post your ad it send me again to the login page and I’m still logged in, it don’t send me to the post an ad page. I think it’s a loop problem.
