You can download Microthemer 3 from “My Downloads” (themeover.com/my-account/) and then update via WordPress by deleting the current version and then installing the zip file you downloaded (you won’t lose any settings using this method).
You will be able to upgrade automatically very soon. We just haven’t enabled this yet because the current version of Microthemer (3.0.16) doesn’t embed the new docs for version 3 on it’s help screen. But as of a few days ago, the new docs are now available online here: https://themeover.com/support/
(we haven’ sent the newsletter about this yet because we want to make sure the new website is working seamlessly first)
Thanks for that, I can’t link my purchases to my Account, probably because I bought Microthemer through Envato. Is there another way to download? I can attach my Envato purchase summary to show that I’ve purchased it.
