All the projects

i developed a transcript management system solution which the signing up and loging in works like this. After signing up at the userside, the newly created account becomes diabled by default and would require validation from the admin before the user can login. after the validation using a toggle switch the user will be able to login successfully and it will take the user to the dashboard and it has been working fine this way. But all of a sudden when the user tries to login after validation it keeps redirecting the user back to login page after entering the username and the password preventing user from signing in. What could be the cause and How do i resolve this issue. There are also other applications on the domain, i will be able to login sometimes, later it keeps redirecting again, the login in process have been so erratic. i have the applications on upperlink server.
