But when I publish the site and try to submit data it throws up. Both with and without uploading a logo.
Any idears ? Please 
Hi,

if not do not forget to publish again after changing it

Kristof.

Update by admin

The dynamic page where my submit form is is set to write. Not read and write because then it changes whats already in the database
