Q:

Not executing programs (*.sh ) with double click in 13.04

I use Ubuntu to host many servers, some minecraft, some cloud services, and many websites.  Unfortunately, after upgrading to Ubuntu 13.04, It will not launch the craftbukkit.sh even though it is set to allow it to execute, it only opens in getit.  I am about to loose it since its been down for 3 hours and person after person comes to me with questions on why its all down.  I am getting annoyed.  
I am running XAMPP 1.7.7 (Not 1.8.1 for various reasons) on my server as well, after it says its loaded, it is not.  Connecting to localhost does nothing.  Can anyone help by chance?  Thanks!  

A:

If you want it to be executed on double click, go to Nautilus > File menu > Preferences > Behavior,  and change the preferences there: set "Executable Text Files" either to "Run executable..." or to "Ask each time" (thanks to Pablo for improving the answer).
