Blank page on the web server - PHS - 04-14-2020
I uploaded my project to the web server, Following the security recommendations, I placed the codeigniter 4 files in the server's non-public directory:
Code:
/home/user/projectAnd in the public directory:
Code:
/home/user/public_htmlI left the codeigniter's public archives:
index.php
.htaccess
robots.txt
In the index.php file, I set the path to the codeigniter's root directory:
PHP Code:
$pathsPath = FCPATH. '../project/app/Config/Paths.php';
After these settings I see a blank page!
What else should I do to make the system work properly?

@PHS,
> What else should I do to make the system work properly?
I would add this line to index.php and ensure it is being called:
file: index.php
Code:
<?php
echo __line__; exit;
// remaining script should not be calledRE: Blank page on the web server - PHS - 04-15-2020
The index and Paths.php file are recognized and are being called!
The subdirectories in the project are with permission 755, and the files with permission 644
RE: Blank page on the web server - John_Betong - 04-15-2020
Have you tried setting the environment to 'development' and...
./app/Config/Logger.php->public $threshold = 3; // 0..9 (none...all messages)
then check the following which should show progress and where the failure occurrs
./writable/logs/log-2020-04-15.log

The very first error concerns something is being written before ini_set();
Search for ini_set(), add the following script and examine what is being written and clear the problem.
Code:
ini_set();
exit; // die; // stop browser execution.Also note if the error log is deleted it will be regenerated until all errors and warnings are cleared. Far easier to only have a few errors showing.
RE: Blank page on the web server - PHS - 04-17-2020
According to information in the error log, the error is in the file:
PHP Code:
vendor/codeigniter4/framework/system/Session/Handlers/FileHandler.php(101): ini_set('session.save_pa ...', '/home/user/pr...')
I went to the file and found this:
PHP Code:
ini_set('session.save_path', $config->sessionSavePath);
Problem finding the directory path to save the session.
I did a test and did a clean install of codeigniter 4 and had the same problem!
Can it be VPS server configuration?
RE: Blank page on the web server - maxxd - 04-17-2020
Check the `Config/App.php` file - $sessionSavePath is right around line 187 - make sure the defined path actually exists on your server.
RE: Blank page on the web server - PHS - 04-18-2020
There is no problem with the directory path. I checked and they are right.
I still think it is some server configuration, because I installed the clean codeigniter in a subdomain and the same problem also occurs.
The point is, I'm not sure if it's a problem with the server or some codeigniter configuration.
RE: Blank page on the web server - PHS - 04-21-2020
Hi, I came back here because I still couldn't solve this problem.
I reinstalled the codeigniter and reconfigured the settings, but I still get a blank page that can be viewed here:
I created a subdomain where I placed index.php. The files remain outside the public_html directory.
I am not receiving error logs. I configured Logger.php to show me all system messages:
PHP Code:
public $ threshold = 9;
But I get just that:
Code:
INFO - 2020-04-21 16:39:58 -> Controller "App\Controllers\Home" loaded.So, I think it must be some simple configuration I am not finding where to do it.
