Some strange behavior on the tab dt5gl?

Feb. 15, 2020, 4:01 p.m.

After pressing the "Input source" button the message: Error: field must be filled in! or after pressing the button "Input value" the message: Error: program source must be filled in! or answers appear to questions that you didn't enter yourself? Then another visitor of this website is just ahead of you! See what happens when you refresh the screen. Or come back later when the environment is free again. In the image, the Gunicorn application server is started with 3 environments (instances, also called workers). I changed that to 1, which explains that there is only 1 environment available for all visitors. Assigning each visitor their own environment still requires some research!
