  • Scanner Options not saved in project file

    Apologize for the double post. I saw someone with a similar issue and posted on that, but I'm not sure if that was the proper way to do this or if I should start a new thread. Please correct me where I'm wrong and delete any post that is wrong. When I start a new project, I select a file to save it to disk (New project on disk) and then I have a default configuration file that has Act...

  • WOFF not recognized as a Content Type

    Most of the times that I see the "Content type incorrectly stated" issue these days it is related to WOFF (Web Open Font Format). This is the issue text: "The response states that the content type is application/font-woff. However, it actually appears to contain unrecognized content."

  • Macro Editor Hang

    Hi, after editing a single HTTP POST request in the macro editor, the form cannot be closed any more. The only way to get back to the main window is to kill the process and restart Burp. Sebastian
