when you go to the trash, it throws it out and asks you to log in again. Where to go?
What do you mean by Trash ?
What operation are you performing ?
Is there an errors in the Log ?
I didn't mean trash ,but shopping cart. The buyer selects the product, adds it to the shopping cart ,and when entering it, throws it on the login form(username and password).
Form to login is shown even if he is logged?
That is for a specific user or all users?
Have you checked the system log?
Are you using a farm (multiple servers)? Maybe you need to use a MachineKey setting in your web.config
I will clarify. since the system administrator left and left the site for me without explanation.
I forgot to translate from Russian)
Then try to set up MachineKey. It's not much effort, and it may solve your problem.
