Critical error in system/Common.php - realpath

Hi,

after loading the homepage i got an 500 error with the following error message in the logfile.

Code:

CRITICAL - 2023-02-24 14:26:45 --> Uncaught ValueError: realpath(): Argument #1 ($path) must not contain any null bytes in /***/codeigniter4/framework/system/Common.php:90
Stack trace:
#0 /***/codeigniter4/framework/system/Common.php(90): realpath('a:3:{s:4:"time"...')
...

What could be the reason for that?

Yes... it looks like it can't understand some of your path.

What is the "base" directory you have CI running out of?

... the *** part of "/***/codeigniter4/..."?

This is only the original path of my webhosting and i don't want to make it public. I masked this part with the ***
