Is anyone else having trouble submitting themes to Tumblr? I have had this problem for two weeks now.
Whatever I try in the "Source code" field here https://www.tumblr.com/themes/new comes back as "Invalid theme HTML".
I have even tried the example markup here https://www.tumblr.com/docs/en/custom_themes and that still returns as "Invalid theme HTML".
Is there something wrong with the service at the moment? Do I need to use a particular combination of browser / OS?! I have tried with Chrome and IE11 on Windows.
I have contacted Support and they have replied asking me to send them a screenshot.
