[ic] Internal Error Server(SOLVED)

[Thomas N. Stefanidis]

Hello all!
    I manage to solve the problem(if i tried to change a page from "Edit
Page" and add some greek, i couldn't save or previe tha page
and i would get an "Internal Error Server").
    Well, i manage to solve it by just clicking the "Save template in
page".
Now i can add whatever i want!
But the question is why??
