Hello there,

I also want to include great tutorials on Common Apache Errors and How To Troubleshoot Common Apache Errors that you can find really useful if you run into an Apache error and you need some help.

https://www.digitalocean.com/community/tutorial_series/common-apache-errors

https://www.digitalocean.com/community/tutorials/how-to-troubleshoot-common-apache-errors

Also, this question was previously posted and answered by Bobby which you can check here:

https://www.digitalocean.com/community/questions/how-to-troubleshoot-common-apache-issues-on-linux-server

Feel free to then share the output of the commands listed in that tutorial.

Hope that this helps!
