Hi there,

I hope you are doing well.

I have moved my prestashop from one server (parallel plesk) to another (1und1).

 

My first page is ok on maintenance mode, while when i am trying to login on admin it stuck when i type username and password as it is on the picture.

I really appreciate you help,

 

Thank you,
