Why Apache is not starting in Windows 10?
This issue commonly occurs when a process like World Wide Publishing Service keeps running in the 80 port of your device. Due to this, the Windows 11/10 operating system does not allow the Apache server to execute, and that way it causes the error.
Can not start Apache server?
There are several reasons your Apache server might fail to run. Something could be blocking the port it uses; there could be another instance of Apache already running; or there might be an incompatibility with the version of PHP you're using in MAMP.
