[SOLVED] Tracy Debugger newest version 4.26.42 - PHP Console does not work anymore

[nurkka]

Here is a quick report regarding one of the newest versions. I tested 4.26.42.
In this version, the PHP console doesn't work anymore: The output window only shows "0:".

Tested on two different hosting providers with three different PW installations.

Downgrading to Tracy Debugger 4.26.26 fixes the problem.

Hi @nurkka- sorry you're having issues. Can you please try if a modules refresh fixes things?

Thanks @adrian , refreshing the modules did not change anything, but I could narrow the issue down a little bit, because it just occurs on websites of the same "type" I was making. I.e. they are using the same set of modules and a lot of the same template code. I think I will now search in my template code first ...

Interesting - does the console panel work when you using it from the PW admin, rather than the frontend of the site?

If you can't figure out the issue, perhaps a trial and error approach of going through the Tracy versions to see where the issue starts occurring might be the quickest in the end. Choose a version in the middle between the current, ie  4.26.34 and if that works, split the difference between it and .42 but if it doesn't, go for .30 - you get the idea and hopefully it won't take long to figure out which one breaks things.

I tested all TracyDebugger versions back to 4.26.26 and the issue starts with version 4.26.27. It is the following line in /panels/ConsolePanel.php:

# /panels/ConsolePanel.php line 406
xmlhttp.open("POST", "/", true);

When I change the line to it's previous version, it works for me:

xmlhttp.open("POST", "./", true);

Could that be some hosting specific issue?
Could it be triggered by .htaccess rules?

Okay, I deleted my ready.php and it works too, so it's likely a correlation with some crazy redirect stuff I am using. I'll test that ...

Edit: Yes, my redirect code in ready.php caused the error. Thanks for your help @adrian – and thanks again for the great TracyDebugger module. I couldn't imagine to ever work without it again!
