Php not loading: white page

Virtualmin
#1

I have a fresh ubuntu 16.04 64 bit vps. I installed virtualmin and I did not install an alternative repo.(so far as I know.) When I visit a php page I just get a white page. I don’t know how to fix this.

My /etc/apache2/mods-enabled/php7.0.conf looks like this. I restarted apache several times that doesn’t seem to help.

<FilesMatch “.+.ph(p[3457]?|t|tml)$”>
#SetHandler application/x-httpd-php

<FilesMatch “.+.phps$”>
#SetHandler application/x-httpd-php-source
# Deny access to raw php sources by default
# To re-enable it’s recommended to enable access to the files
# only in specific virtual host or directory
Require all denied

Deny access to files without filename (e.g. ‘.php’)

<FilesMatch “^.ph(p[3457]?|t|tml|ps)$”>
Require all denied

Running PHP scripts in user directories is disabled by default

To re-enable PHP in user directories comment the following lines

(from <IfModule …> to .) Do NOT set it to On as it

prevents .htaccess files from disabling it.

php_admin_flag engine Off

My apache error log looks like this:

Virtualmin is really buggy these days. I tried to install on Ubuntu 16.04 with Nginx, but it failed multiple times. And there’s also a webmin bug on Ubuntu 14.4 with Nginx. Looks like time to find new CP.

#3

I don’t expect virtualmin to be bug free. I’m very grateful that I can use it for free.
I already used some other control panels and virtualmin is by far the best.
There is always something wrong with the other control panels, lack of support or updates, unsecure, buggy, limited features etc. At the moment I’m happy with virtualmin. I’m not switching.

#4

Howdy,

Well, Nginx is a bit of a different animal. We recommend Apache. While Nginx should work, it’s more likely to have some occasional issues that arise. I know Jamie is working on the bug report you commented on, hopefully that issue will be resolved shortly.

As far as Apache goes – we do expect Apache to work out of the box. The issue here may be a PHP issue, but we can dig into that a bit more.

lolbro, could we maybe simplify things a bit and see if PHP in general is working? I’m seeing some errors there that suggest maybe you’re seeing an issue specific to that application, or maybe even just a missing PHP module.

Could you create a new file named “test.php”, and in that file, add the following contents:

<?php phpinfo(); ?>

When, when accessing test.php, does that work as expected?

#5

Okay, try running this command:

apt-get install php-mbstring

And then restart Apache:

service apache2 restart

After that, what happens when you try to access phpMyAdmin?

-Eric

#6

Intresting, yes phpinfo works.

But for instance php my admin doesn’t. It is just a white page.

#7

Thank you very much! The problem is resolved after I ran the command! :slight_smile:
