Ok, I have a form that passes data onto another page that validates the form data and executes the queries to store the data in the database. Depending on whether the data is valid or not the user is redirected to an appropriate page.
This worked upto yesterday. Now, when the form is submitted everything up the point of the reaching the header command is executed (I can test this by querying the db and also inserting test echo commands to check the if branching). But, instead of redirecting the user, all I get is a blank white screen (there is no source if I try to view it)- the header command doesn't work.
