1. fix the webforms, it always shows a lot of errors when I try to create them. Basically the creation process is fine, but after I hit the save button the form is not working and if I want to edit all the errors appear. I want to create 2 different webforms by myself, but I cannot due to the errors.
2. Furthermore I would like to use the customer portal. Customer should be able to log in and see his own record, so I assume I need to set portal user to yes?
Please install customer portal and configure it that all users which are set to "portal user" do have access to contacts and projects.
