My Apache Server will not start?
The most common problem with Apache Server not starting is another mysql service running on the same port. To check this
- Quit MAMP PRO.
 - Open the Windows Task Manager.
 - Go to the Processes tab.
 - Type “httpd” into the search field on the top right.
 - Quit every process you find after your search.
 - Restart MAMP PRO.
 
If Apache still refuses to start check the log file for error messages.
