Hi,
What is the version of the prestashop you are using? Prestashop 1.5 create admin folder with admin followed by some number and prestashop 1.6 version create admin followed by unique text for better security of the back-office.
I can see you admin folder name "adminmysite"
Have you change the admin folder name?
