I’m having the same issue since the 4.4.1 update – I had my permalinks set to /%category%/%postname%/, which worked fine for a few months’ worth of previous WordPress versions. Since the 4.4.1 update, the site’s home page became unreachable, throwing a “too many redirects” loop. Interestingly, other pages and posts on the site were still reachable – just not the home page.
Setting the permalinks to their default, the post ID, allows me to reach the home page. I tried deleting the .htaccess file, then setting the permalinks back the way they were, but this did not solve the issue for me – pages and posts are still accessible, but the home page still is not. I looked at the old and the new .htaccess files – besides a linebreak at the beginning, they’re identical anyway.
I also deactivated all of my plugins to get a cleaner test base, but still have not found a solution, unfortunately. I have about a dozen other WordPress sites, all of which work fine – I’m not sure what’s unique about this particular site. I’m going to continue to investigate and will make another post if I find a solution – but if anyone has other advice, I’d really appreciate it!
