I tried to stop the apache service in xampp, but it does not stop from running and it shows up an error "Busy...ERROR: -1" What is the cause of this problem of how do I resolve this? Thanks in advance.
What OS are you using? Are you using the XAMPP control panel?
In windows press
Start
Run
Type "Services.msc"
Find the "Apache" service
Right click and stop
I find i get this error if i start the apache service without the control panel but try to stop it with the control panel.
