Install in subfolder and subdomain error

Hello all,

Everything generally worked fine with my wordpress installs in subfolders but I have been working with the JSON API and I have been making function calls not likely used before. At least that is all I can figure.

After a series of errors and attempts to resolve by including the necessary resources I finally hit the wall with the final ABSPATH error:

Warning: require(ABSPATHWPINC/option.php): failed to open stream: No such file or directory in /home/XXXXXX/public_html/XXXXXX.com/wp-includes/functions.php on line 8

No resolution –
The error prior to that was:

Fatal error: Call to undefined function wp_parse_args() in /home/XXXXXX/public_html/XXXXXX.com/wp-includes/class-http.php on line 400

resolved with – include(“wp-includes/functions.php”);

Prior to that:

Class ‘WP_Http’ not found in /home/XXXXXX/public_html/XXXXXX.com/wp-includes/http.php on line 26

resolved with – include(“wp-includes/class-http.php”);

prior to that:

Call to undefined function wp_remote_post() in /home/XXXXXX/public_html/XXXXXX.com/testput.php on line 11

resolved with – include(“wp-includes/http.php”);

So as you can see I was just hacking through it and it pretty clear there is something wrong with the PATH for the resources. How this hasn’t shown up before is a mystery, but here I am seeking some advice.

Could the fact this is installed in sub directory be the cause of these issues? I am able to pull data no problem, but can not POST. FYI i am not POSTing to WP posts or pages but into a database within WP.

Test Script:

<?php

	include("wp-includes/functions.php");
	include("wp-includes/class-http.php");
	include("wp-includes/http.php");

	$url = "www.XXXXXX.com/wp-json/frm/entries";

	$response = wp_remote_post( $url, array(
	'method' => 'POST',
	'timeout' => 45,
	'redirection' => 5,
	'httpversion' => '1.0',
	'blocking' => true,
	'headers' => array('Authorization' => 'Basic ' . base64_encode( $api_key .':XXXXXX' )),
	'body' => json_encode(array( 'XXX' => 'Test',))
    )
);
echo $response
?>

Thank you for your consideration.
