Does anybody meets the problem as mine that the workspace doesn't work?

After I saved the Workspace provided, I try to preview, but nothing expected happened no matter how I change the code. It has been so for quite a long time, but I don't want to bear it any more. Dose anybody meets the same problem? Anybody knows how to fix it? Thanks in advanced!!!

Please post a snapshot to your workspace. You do that by clicking the camera icon on the upper right and following the steps until you get a URL you can copy and paste here. I am willing to bet you have an error that is preventing the preview.

Thank you, Sumner. This time I chose 'launch different workspace' rather than the green button 'launch it' after I clicked the 'launch workspace' button. Then the preview finally shows what I expected for one time. Now the problem is that if I changes code to see effects, then I save and preview again, however the preview doesn't have any changes. i.e. the preview doesn't reflect the code changes at all. I got the URL: https://w.trhou.se/kr9ieftd1g as you indicated , and I am testing using the course of 'Managing Errors' from the 'PHP & Databases with PDO'.

Here is an example tragedy that I went through. First I tried the correct code, then preview shows "object(PDO)#1 (0) { }" which is as I expected, then I tried giving wrong code purposely, preview gave me the same message "object(PDO)#1 (0) { }". So I leave it aside, the trick is after 15mins, I preview again, it gave me message "SQLSTATE[HY000] [14] unable to open database file" which is as I expected, then I tried and used correct code again, but preview still gave me "SQLSTATE[HY000] [14] unable to open database file". So I totally don't know the temper of this workspace. Sometimes it works and sometimes it acts like out of control.
