Following Problem was happened to me:
I had a HTML form to send text data to the webserver. Because it was only text data, I used the enctype „text“.
<form name="formname" enctype="text" method="post" action="saveData.php">
This works in every browser like IE, Firefox and Safari. But I never tested it in the Google Chrome browser.
The form had some mandatory fields. If not all of these fields are filled, the not filled fields are colored red and the hint is shown, that all mandatory fields must be filled. Then a user called me and told me, that he is not able to register. He filled all fields and pressed the register button. Then the form was shown again, all fields were empty and all mandatory fields were colored red.
