Was running into this problem, fixed by disabling that setting. Thanks!

Sorry peeps, still no joy on the “too many redirects” issue. I’ve swapped themes in and out, eliminating my recent theme work as the source. I’m fairly sure it’s a server config issue. Been trying to contact with tumblr support, but only getting unrelated canned responses back so far.
update: there’s a setting: ’Use descriptive URLs’ under the Advanced tab on your Customize screen. Turning this off seems to have fixed the problem. Thanks to Renee at tumblr support for the help.
