I have written Event Receiver for a list on my local site on its item added event in that event receiver it creates subsite under a top level site. And updates a url in the list. This functionality is working fine on my own development machine but when i deployed wsp to another machine it is not working why does that happen so? Even I can't debug that wsp, what is the way to find out error?
Configure ULS Logs and try to find events relative to your solution.
