I cannot access Desktop & some other features!

[AhmedS]

The problem is that if i log in to the Plesk it gives me an error message that this page cannot found ... (http://89.144.96.61:8880/?previous_page=login_up) and i have to delete the (?previous_page=login_up) and press Enter to go in ... even after that i cant access the Desktop, it tells me: (Operation failed
The operation you were performing failed. You can retry the operation with or without changing its parameters. You may also want to report this problem to our support so that we could help you as soon as possible)

Also if i want to do anything like adding a new user or creating a new domain it goes to the same error page .. which put me in annoying position with my client!!

Please help me ,, or at least tell me what to do.

Thank You.

apply Plesk Reconfigurator and see if that helps
