Adding employee results in 503 page

[vysakhv90]

Every time I try to add an employee, it throws me 503 error. FYI - this is a fresh installation of sentrifugo and I was able to add one employee which is shown in "Add reporting manager". However, employee listing says no employees.

And while I didnt see any errors while creating department, I dont see the same in Leave management options (for example). Can someone quickly assist on this please?
