What Plugin does this relate to? What version of the Plugin?

What steps will reproduce the problem? 1.install pystudio 2.configure dirvar_py.cfg and .pylintrc 3. uninstall previously installed pylint plugin

What is the expected output? What do you see instead? Doc says that only Analyze button should appear. I see it and the Pep8 Check button. Clicking on Pep8 Button generates message: "FATAL ERROR: No Pep8 configured or found" I assume the message is looking for...?

What version of Editra are you using? On what operating system? 0.7.20 on Windows 7

Maybe this is all OK and I am confusing Pep8 checker with Pylint.

Please provide any additional information below.

This is all ok. I installed pep8 checker. Everything works as it should.

Yes, the pep8 check was added in a recent update to the plugin so there is both the pylint and pep8 checkers available now. As you found to use the pep8 check you need to have the pep8 module installed.
