I have 3 WordPress installed on my Ubuntu in
/var/www/html directory. There was no issue from last two years.
But recently while I am installing another script in the same directory, I had to purge and reinstall the apache2.
And after that, I am unable to access my all websites. It says "Unable to connect"
When I entered IP address it's showing the Apache server home page instead of 3 directory page that was shown before.
I have tried to restart the Apache server and its running well but still no result.
