Error with Apache2 on Ubuntu

[Stentorian]

And again... trying to experiment with newer versions of PHP gave me another error.

Any help would be awesome!

Have you tried checking the processes listening on ports 80 and 443?

As far as I can see, no there isn't anything running on port 80 or 443.

Never mind, I found it. Here they are:

other_vhosts_access.log

error.log

access.log

Any reason you're using Apache over nginx?

Because I am following a tutorial and that's what they recommend. I don't fancy changing anyways. I am just looking for a solution to my problem.

 

I also disabled nginx from port 80 and 443 because of it and Apache running on the same port and it would be even more hassle changing access to ports over.

show me your apache conf

The most common way to misconfigure something like Apache is following an old tutorial, are you sure it is "updated" enough? Software can change and misconfigured Apache could be the reason of why is crashing
