Erroring: Skipping loopback test: A valid URL was not provided.

A valid URL was not provided.

This is a WordPress core error message from the WP_Http class (wp-includes/class-http.php).

The iTSec plugin loopback test is nothing more than a wp_remote_post() call to the admin-post.php script of your site (https://egpower.com/wp-admin/admin-post.php).

I would recommend to use the http_api_debug action hook to verify the value of the first argument ($url) passed to the wp_remote_post() call (as well as the values in the $parsed_args array) for the loopback test.

To prevent any confusion, I’m not iThemes.

Hmmm, not sure whether this is relevant for the issue reported in this topic but egpower.com seems to have a display problem when accessing the login page using egpower.com/wp-admin … all the images/styling on the login page is not available.

However it’s fine when using egpower.com/wp-login.php …

Note the iTSec plugin makes use of admin_url( ‘admin-post.php’ ) snippet of code to get the first argument ($url) for the loopback test wp_remote_post() call …

Could be that the admin_url() function produces an invalid url …
