This is very rarely, if ever a sensible way to proceed.
How do you know you won't end up right back where you are only without
anything to analyse?

Get to the root cause of the problem and solve it from there.

Throwing
extra layers at the problem won't help you understand it any better.


It sounds like you have some kind of apache module issue. Maybe try
starting from the provided http config file (save your copy and get apt
to reinstall the provided one) and then build it back up piece by piece
until you work out the directives that are broken.

Then consult the
Apache documentation to work out which modules they are from. Then work
out whether those modules are installed and enabled and at the correct
version. Go from there.
