    1. CO404: what URL are you accessing? And perhaps other parts of your config are incomplete? Assuming there's a default `index.html` , do you get to see that one at least when visiting http://127.0.0.1/ ?

    2. COi open /localhost/cgi-bin/script.py - the actual path where the script is and where apache has access. There is no index.html/index.php/index.else

    3. COSurely you mean `http://localhost/cgi-bin/script.py`? My apache configuration is a bit rusty, but possibly, you can leave off the .py extension there as well. But for your (and our) sanity, it'd be good to put an (empty) index.html file in `/var/www/` and see if you can at least find that.

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).
