As the title says, I am facing this when trying to install Python extensions in Burp. Is it something related to jython environment variables? Thanks This is the complete traceback: Traceback (innermost last): File "<string>", line 1, in ?

Hi Alex, Thanks for your message. We haven't observed this issue before. However, we noticed that your version of Jython is version old - 2.2.1. Most people are using 2.7.0 so I suggest you try upgrading Jython first. Please let us know if you need any further assistance.
