Blank screen after clean installation

[Matze]

Hi

I'm trying to install a page on https://www.arsys.net 

(It's not my first PW installation, i made dozens of them before on different servers. On this hosting for the first time. This error i never had before …)

√  htaccess works, (except Options -MultiViews, has to be commented)

√  php 8

√  Database connection works

I'm going through the clean installation process step by step

Everything works fine

After clicking the last step … the following page looks like nearly empty (attached screenshot, header but no content)

If i try to opne the root of the page it's blank white  (http status code 500)

config errors are set to true
 

Any ideas where to start searching for this strange problem?

Is there anything in /site/assets/logs/errors.txt (or exceptions.txt)?

I will usually turn on error_reporting and display_errors in index.php or ready.php:

error_reporting(E_ALL);
ini_set('display_errors', '1');

Thanks for this idea. I pasted it in index.php and there is still no error message.

Interesting thing - if i put

<?php namespace ProcessWire;
error_reporting(E_ALL);
ini_set('display_errors', '1');
echo 'test';

it outputs "test" on the blank page. Status code is still 500.

"Allowed memory size exhausted" is often a sign of a loop somewhere, but in this case it's more likely just an issue with your hosting environment or PHP configuration: 16777216 bytes = 16 megabytes, which is quite a small amount of memory. It's not surprising that it keeps running out.

Is this an actual limit of your hosting package, or have you configured PHP to only use 16M? Either way I would recommend raising the limit to at least 64M, or preferably 128M.

Yes! Thank you very much. I found a way to raise it up to 512 MB in the Control Panel of the hosting. Now it works.

I wonder if PW should check the memory limit during install?

Sounds like a good idea ?
