I had a similar problem, I was trying to run the application in debug mode but the "debug" flag was set to "false" on the compiler settings. Basically the IDE was launching a debugger instance that would never receive a connection from the application, so when you try to launch another application (on debug mode), it will complain with the error you mentioned.
Try to check if you have the "debug" flag active on your compiler arguments: "-debug=true"
Thanks for your response. Did you just add '-debug=true' as an additional compiler argument?
Yes, in my case that was all I did.
I had this problem after changing the compiler arguments to '-debug=false' in order to generate a production release from the application. When I came back to make some developments I forgot to change it back to '-debug=true', and that was how I got the error message.
Well I appreciate your response, but unfortunately your suggestion didn't work for me. Thanks for your time.
May I ask which browser are you using to debug the app?
If you are using IE, can you try another one (Firefox, Chrome, Opera)?
I tried IE, Firefox, and Chrome; same deal across-the-board. The only way I get the debugger to run is by closing FB and re-opening each time I want to run it. I've Googled the problem and nothing I'vve found has helped. Well I'll keep looking.
I have the same problem.
Have you solved?
Thanks in advance.
