    <p>I was using an ASP.NET Wizard control for adding news users to the web-based application that I developed. Everything works well and fine. Now, I got a new requirement from the Admin of the system which is sending an email notification to the new user telling him that he has been added to the system. I added the Mail function to my code and it works, however, in the IE browser I noticed the error icon at the left bottom corner and I don't know why. </p> <pre><code>Problems with the Web page might prevent it from being displayed properly or functioning properly....

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
