I experienced the problem while configuring ssl on WAMP server that whenever I tried to restart the Apache server it failed after I did some configurations.
When I was going to see the apache logs I did not see any error log being generated. This kept me finding the solution for hours.
Actually, when working on windows and having the apache running as windows service, you have the option to look at the windows operating system’s ‘Event Viewer’.
1. Go to Control panel
2. Open Administrator Tools
3. Open Event Viewer
4. Under Windows Logs menu item in the left sidebar you can click on ‘Application’
5. After doing the step 4 you will find the logs in the right panel of the screen and there you can see the events for the apache server logged where the ‘source’ column shows ‘Apache Service’ in the row.
By selecting the particular row you can see the details of the event in the lower panel.
