Multiple "already defined" errors in php logs

[fleagle]

After installing, I cannot access admin. I have installed/reinstalled 3 times. Initially I get a 500 error, but when I view the php logs I get several lines that all say something like:

[php7:notice] [pid 17524] [client ::1:62297] PHP Notice:  Constant _PS_GENDERS_DIR_ already defined in /prestashop/config/defines.inc.php on line 121

it just goes on and on and on and on. 

Any ideas?

these are php  'notices' and would not cause php script to end nor do I think they have anything to do with your access issue.

use ftp and ensure ps debug mode is enabled (search forum on how to).  We want to revisit the 500 error, recreate and get underlying php error.  Also you can contact your hosting company as post install ps usually runs pretty good.

you rename the admin directory yes?  and dare using that in your url to access back office?

you deleted the install directory?

So I actually hadn't renamed the admin directory or removed the install directory. I had hoped it would be that simple. But I'm still getting the exact same errors.

I'm actually running this on my MAC OSX Apache Server. 

PHP version 7.1

MySQL version 5.6.41

UPDATE

So I tried commenting out:

//require_once(__DIR__.'/config/defines.inc.php');
//require_once(__DIR__.'/classes/PrestaShopAutoload.php');

in the autoload.php file.

 

This actually loaded the admin login screen and allowed me to login.

 

But once I logged in I got this (from debugger):

Level	Channel	Message
CRITICAL20:09:58	php	Fatal Compile Error: Cannot declare class ComposerAutoloaderInit3e8f95d9b4b1dbdd6f7eb126a99fd4d2, because the name is already in use

I 'highly' recommend using a hosting space...to run localhost requires a lot of little tweaks and to be honest I stopped using localhost years ago.  Also you will be working in an environment that will not reflect production.
