Diagnosing Wordpress infinite internal redirects (after installing theme / plugin / demo content)

gistfile1.txt

Line 1305 in wp-includes/pluggable.php you can find; 

        function wp_redirect( $location, $status = 302, $x_redirect_by = 'WordPress' ) {

that is probably what executes the redirect, so just add a 

        die($location); 
        
        
to see if this is indeed the culprit. 

If it is, add this before the die();

        debug_print_backtrace();

Which results in something like: 

#0  wp_redirect(https://www.domain.com/blog/, 301) called at [/var/www/html/wp-includes/canonical.php:799]
#1  redirect_canonical(https://www.domain.com/) called at [/var/www/html/wp-includes/class-wp-hook.php:307]
#2  WP_Hook->apply_filters(, Array ([0] => )) called at [/var/www/html/wp-includes/class-wp-hook.php:331]
#3  WP_Hook->do_action(Array ([0] => )) called at [/var/www/html/wp-includes/plugin.php:474]
#4  do_action(template_redirect) called at [/var/www/html/wp-includes/template-loader.php:13]
#5  require_once(/var/www/html/wp-includes/template-loader.php) called at [/var/www/html/wp-blog-header.php:19]
#6  require(/var/www/html/wp-blog-header.php) called at [/var/www/html/index.php:17]

So now we can figure out why it tries to redirect by checking that code.
