White Blank page after installation process

joonn · April 23, 2023

I tried to install Froxler on to a fresh stock Ubunu 22.04

After i got to step 3, which is finishig the installation, i got forwarded to xxx.serverip.xxx.xxx/froxler where i get just a white blank page.

I have nothing changed on the ubnutu installation the first thing what i did was installing froxler.

It was just the gd liabary missing for php, that was the only thing which i had to install before.

The thing is forgot to copying it but, when installing froxler trough SSH/Terminal i got a similar looking error like in the php error logs.
Something like: unexpected identifier "wRGv", expecting "]"

Here are some the error logs from php:

Man kann auch ruhig auf Deutsch antworten, ist nur EN für SEO falls mal jemand über das selbe Problem stolpert.

So what content is in /var/www/html/froxlor/lib/userdata.inc.php on line 8

d00p · April 24, 2023

yes, that's it. And escaping wont help as it alters the password. Try the following syntax (which we will ship with the next version):

[...]
$sql['password']=<<<EOT
dein'password'mit-einfachen-anführungsstrichen
EOT;
[...]

d00p · April 24, 2023

no, thats not valid nor correct.

<?php
// autogenerated froxlor file

$sql = [
        'debug' => false,
        'host' => 'localhost',
        'user' => 'unrprivileged_xxx',
        'password' => <<<'EOT'
lorempasswordlorem
EOT,
        'db' => 'dbnamelorem',
];
$sql_root = [
        '0' => [
                'caption' => 'Default',
                'host' => 'localhost',
                'user' => 'froxlerfullprivuserlorem',
                'password' => <<<'EOT'
lorempasswordlorem
EOT,
        ],
];

for syntax, see here: https://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.nowdoc

That seems like the place where the SQL user, password etc. is safed.

I used a ' sign on the beginning of my password but the string is enclosed in two ' ' like 'password' but in my case ''password' that seems to brake the code.

Maybe there should be a check for that occasion?

joonn · April 24, 2023

I don't fully get it how to write it , but that seems like a perfect fix.

Is that right?

<?php
// autogenerated froxlor file

$sql = [
        'debug' => false,
        'host' => 'localhost',
        'user' => 'unrprivileged_xxx',
        'password' => [''lorempasswordlorem']=<<<EOT,
        'db' => 'dbnamelorem',
        EOT;
];
$sql_root = [
        '0' => [
                'caption' => 'Default',
                'host' => 'localhost',
                'user' => 'froxlerfullprivuserlorem',
                'password' => 'lorempasswordlorem',
        ],
];

Untoched code for you to alter comfortable.

Spoiler

<?php
// autogenerated froxlor file

$sql = [
        'debug' => false,
        'host' => 'localhost',
        'user' => 'unrprivileged_xxx',
        'password' => ''lorempasswordlorem',
        'db' => 'dbnamelorem',
];
$sql_root = [
        '0' => [
                'caption' => 'Default',
                'host' => 'localhost',
                'user' => 'froxlerfullprivuserlorem',
                'password' => 'lorempasswordlorem',
        ],
];

Hmm seems to we getting further

Now i get instead of a blank white page this error:

Not Found

The requested URL was not found on this server.

Apache/2.4.52 (Ubuntu) Server at 123.xxx.xxx.xxx Port 80

I looked also up the useres in my MariaDB and I have the unprivileged user created by Froxler 3 times in it.

Is that normal? It didn't even know that it is possible to have the exact same username 3 times oO

a 404 not found is another error. Be sure the DocumentRoot in the virtual host config points to the correct location.

I doubt you have the same database user 3 times, most likely the "Hostname" value differs (e,.g. one user for 'localhost', one for '127.0.0.1' and maybe one for your ip address)

joonn · April 24, 2023

Hmm I have looked it up, and never touched anything about virutal hosts it is just by default DocumentRoot /var/www/html

Maybe something went wrong while installation since, the password was not "readable" at that point?

d00p · April 24, 2023

Well if the lib/userdata.inc.php file has been created (and you most likely ran the finalizing command from the installation) froxlor is installed. Just check your webserver config folder for possible generated virtual host configs. Or alternatively nopaste contents of the folders - I can only guess at what stage you are right now and what works and what not. Important to first adjust your lib/userdata.inc.php so the database connection is correct

joonn · April 24, 2023

Yeah userdata.inc.php is fixed already, like told it made also an effect.

But now i am stuck a the next step.. here the configs.

and you get the 404 error when opening http://ip/froxlor ?

Verify your version of php, if your use froxlor 2, use php 8.1 or higher
