Hv changed Github Repository of Joomla Patch Tester to:

(After checking & fetching) Got the list of previous issuing tracker, but not from Web Links.

Checked also: https://github.com/joomla-extensions/weblinks (Part of Patchtester Component)

I honestly don't know how you can test Weblinks.

Thanks ! Now I understand how help works :D.

Honestly, I don't know how to use patch tester to test weblinks, too, so I applied the changes manually to test it. Will try to play with patch tester later to see if it could be used to test weblinks PR.

Thanks @Bakual for the PR and thanks @ChristineWk for willing to help with testing.

There is a third variant for help screens where the extension installs the help files directly with the extension. I don't understand yet how that works, probably broken anyway 😀
