A quick note for anyone experiencing this ERR_TOO_MANY_REDIRECTS issue I spent half the day trying to fix today, since I found no blogs on it.
Apparently, Chrome was the only browser throwing this issue. I had a client’s e-commerce site (WordPress and WooCommerce) which suddenly started throwing Too Many Redirects errors today. Safari, Firefox, and IE all worked fine.
Typically, I would go to wp-admin first to try and fix this, then check the siteurl and home values in the options table in the WordPress db. Both, in this case, were fine. Googling turned up no help.
I wound up finding the issue was in the WooCommerce setting. Solution: visit yoursite.com/wp-admin/admin.php?page=wc-settings&tab=checkout, and make sure Force HTTP when leaving the checkout is UNchecked.
Problem solved. Hope this helps someone. 😉
