Hi,
I have this problem too, I installed the 3.1.0 XAMPP now, and when I start the apache, it won't want to work, automatically stop running. I get this message in the control panel:
20:43:40 [Apache] Status change detected: stopped
20:43:40 [Apache] Error: Apache shutdown unexpectedly.
20:43:40 [Apache] This may be due to a blocked port, missing dependencies,
20:43:40 [Apache] improper privileges, a crash, or a shutdown by another method.
20:43:40 [Apache] Check the "/xampp/apache/logs/error.log" file
20:43:40 [Apache] and the Windows Event Viewer for more clues
But the error.log is empty.... I tried changeing the ports, but still doesn't work... Any other idea?
