install on local in subdirectory please

hello I am quite expert with installation of zencart, but....
now I have to test it on local and on local folder...
I know that I did a wrong work with path of config.php files, I would install on folder zencart under
/opt/lampp/htdocs/zencart
on my local pc with ubuntu
db: zencart
user: root
password NO password

obviously I have lampp started but I have 500 error...
I attach 2 configuration files, I hope someone says to me right path, please

my includes>configure.php

thanks in advance

I have to modify entirely my steelsheet so I have to try on local... :flex:

define('HTTP_SERVER', 'http://localhost/zencart');
define('HTTPS_SERVER', 'https://localhost/zencart');

should be

define('HTTP_SERVER', 'http://localhost);
define('HTTPS_SERVER', 'https://localhost');

and

define('DIR_WS_CATALOG', '/');
define('DIR_WS_HTTPS_CATALOG', '/');

should be

define('DIR_WS_CATALOG', '/zencart/');
define('DIR_WS_HTTPS_CATALOG', '/zencart/');

thanks but it doesn't work...
any idea?
:frusty:

so I solve, I moved on / root on /htdocs folder, so I have no problems with installation on subfolder
then I have imported sql into database, because I saw error 1146 and I saw a post that said solving importing sql.

But it remained the problem that I didn't acceed to admin login, for problem 1146, I saw another post where it says that was a prefix database on configure.php and....:blink: what stupid I am, I have seen that in admin/includes/configure.php was a different prefix table.....

so I solved all, I guess that it was wrong installation on subfolder because of that wrong prefix

thanks for patience :clap:
