I uploaded a file and realized I had to change something before submitting it so I reuploaded it (I think twice).
Now when I try to upload the file an almost blank page appears with only the text :

Fatal error: Uncaught [[o:Exception]:"java.lang.Exception: Invoke failed: [[c:Session]]->createNewSession((o:int)[o:Integer]). Cause: burp.domain.PermissionException: Too many unsubmitted sessions, please reuse a previous one or cancel them before creating new ones VM: 1.8.0_92@http://java.oracle.com/" at: #-30 burp.domain.Session.createNewSession(Session.java:502) #-29 sun.reflect.GeneratedMethodAccessor177.invoke(Unknown Source) #-28 sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) #-27 java.lang.reflect.Method.invoke(Method.java:498) #-26 php.java.bridge.JavaBridge.Invoke(JavaBridge.java:1044) #-25 php.java.bridge.Request.handleRequest(Request.java:417) #-24 php.java.bridge.Request.handleRequests(Request.java:500) #-23 php.java.bridge.JavaBridge.handleRequests(JavaBridge.java:150) #-22 php.java.servlet.RemoteHttpServletContextFactory.handleRequests(RemoteHttpServletContextFactory.java:262) #-21 burp.frontends.phpjavabridge.PHPJavaBridgeServlet.processRequest(PHPJavaBridgeServlet.jav in /mnt/hosting/www/burp_production/libraries/php-java-bridge/Java.inc on line 196


How do I "reuse a previous one or cancel them before creating new ones" ?

I couldn't find such an option anywhere.

You have been talking to BURP Core. It speaks in wonderfully monochromatic gibberish sentences when it wants to say anything...

BURP has had to implement a number of self-defense mechanisms over the years. One of them is that you cannot create more than 19 sessions without submitting them.

Currently the only way to reuse and manage unsubmitted sessions is through a UI in Blender which is not available for public use at the moment and through a remote API. There is no way to do it through the website.
The reason why a session can even BE in a state where it has been created but not yet submitted is that the session creation system is way more flexible than what is shown in the current "Submit session"-wizard on the website right now.

Since it is perfectly normal to have a small amount of unsubmitted sessions build up over time (your example is a good one) I've added a feature request to the todo-list to have the system automatically time out and reject those sessions after a while if they have not been touched.

As for right now: I've rejected all unsubmitted sessions manually.
