phpinfo() showing blank page on ubuntu18.04

Question

I installed phppgadmin using this tutorial. How to Install PostgreSQL and phpPgAdmin on Ubuntu 18.04

The index.html file is showing fine that comes already installed.

But when I made a php file to display phpinfo();, it shows blank page.

This is the output of root@pan0xxx:/# tail -f /var/log/apache2/error.log

root@pan0138:/# tail -f /var/log/apache2/error.log

EDIT

Output of /# tail -f /var/log/apache2/error.log after installing php separately.

try to remove your index with type `sudo rm -f /var/www/html/*`and restart your pgadmin, and did you check your email sir? — abu-ahmed al-khatiri, Oct 10 '18 at 09:25
@abu-ahmedal-khatiri: I will check sir. Just give me little time. Thank you for prompt ! — XCeptable, Oct 10 '18 at 11:17
@abu-ahmedal-khatiri: it's not pgadmin, phppgadmin. I tried install using this tutorial: https://www.howtoforge.com/tutorial/ubuntu-postgresql-installation/ — XCeptable, Oct 12 '18 at 08:35

What I did is something like this:

sudo a2enmod php7.2

If you get an error message showing conflicts, such as in my case I had: mpm_event error, you do this:

sudo a2dismod mpm_event

you'll get messages like "apache2 crashed!" or something. Don't worry. Do the same a2dismod for all errors. Once done, execute:

systemctl restart apache2
sudo a2enmod php7.2
systemctl restart apache2

And that should do the trick! Good luck!

For me, under Ubuntu 20.04, it was

sudo apt install libapache2-mod-php
sudo service apache2 restart

That fixed the phpinfo() being empty.

From the tutorial I followed, link above, I used this command: sudo apt -y install postgresql postgresql-contrib phppgadmin Do you think it will not have installed php ? – XCeptable Oct 08 '18 at 14:50

No it will only install following additional packages will be installed: postgresql-9.5 postgresql-client-9.5 postgresql-client-common postgresql-common postgresql-contrib-9.5 sysstat – Mayur Bhandare Oct 09 '18 at 05:03
you need to install php seperatly – Mayur Bhandare Oct 09 '18 at 05:04
I installed and restart the apache but it still shows blank page. The output of # tail -f /var/log/apache2/error.log now I added to OP. – XCeptable Oct 09 '18 at 09:09
