createapi2.php does not run properly with WordPress 4.4.x

[bobbingwide]

When createapi2.php is run in a WordPress 4.4.x we get the following message.

Fatal error: Uncaught Error: Call to undefined function add_action()

Problem explanation

There is a call to add_action() in formatting.php This assumes that plugin.php has been loaded. oik-batch loads formatting.php before plugin.php

Solution

swap the lines around.

That's not the only fix. There are many more include files in 4.4.2 than there were in 4.3.x In order to fix: Fatal error: Uncaught Error: Class 'WP_Http_Encoding' not found we need to include a load more files prefixed class-wp-http after class-http
