Prevent WordPress home page redirect after WP 4.4.1
It looks like the new version of the WP enforced the redirect on homepage. My issue was resolved with the remove_filter('template_redirect','redirect_canonical');. I wasn't able to see the change in effect after I applied that fix because the browser cached it somehow. I tested it on the Private mode, and it worked. I had to clear the cache to see it working.
I ran into the same issue and got i fixed, thanks to your answer. However, what are the implications of removing that filter? It sound important by name, so did you experience some new issues so far?
PS: i would have posted a comment to the previous answer, but my stackoverflow points are below 50...
LTDInvestments is actually correct. In your wp-config.php, ensure that 'WP_HOME' and 'WP_SITEURL' have values which are lowercased.
This fixed it for me; I guess case-sensitivity is something you should mind throughout your wp-config.php and wp-admin settings.
