I forgot to clarify that I am installing in PHP8

@Vlad7
Always you get Error 500, you must enable error logging to be able to check what are errors behind.
PHP 8 is OK.

I was also getting Error 500
Then, I enabled Error Logging.

Error is as follow:

Fatal error: Uncaught Error: Undefined constant "OC_ADMIN_FOLDER" in F:\ProgramFiles\Xampp\htdocs\OSCLASS\oc-includes\osclass\helpers\hErrors.php:108 Stack trace: #0 F:\ProgramFiles\Xampp\htdocs\OSCLASS\oc-load.php(42): osc_get_absolute_url() #1 F:\ProgramFiles\Xampp\htdocs\OSCLASS\index.php(25): require_once('F:\\ProgramFiles...') #2 {main} thrown in F:\ProgramFiles\Xampp\htdocs\OSCLASS\oc-includes\osclass\helpers\hErrors.php on line 108


How I solved this?


I added
define('OC_ADMIN_FOLDER', 'oc-admin');
in "oc-load.php" before if (!file_exists(ABS_PATH . 'config.php')) {

Re-download 8.0.0, it was fixed already.
Issue was in hErrors.php, additional check has been added to identify if OC_ADMIN_FOLDER is defined or no.

Oops! Sorry!!!

I download v8.0.0 - a month ago and did fresh installation today.
After using latest v8.0.0, it is working great.

Thanx 

Glad to hear that, thanks for confirmation
