Just purchased the theme. When I click on “Appearance -> Customize” the admin page will not load. Just get a blank page with a spinning circle in the middle and says “Customize Loading…” at the top. I am using WordPress 4.3.1 and the current version of Origami.
I’ve checked the case and it’s indeed a bug; it stems from a compatibility issue between one of the included plugins and the newer version of the WP Customizer. I’ve added a fix to the theme and submitted an update to ThemeForest – it should be available for download within 24-48 hours, as soon as they review the upload. The new theme version is 1.3, and it contains this fix, together with a couple of other minor fixes. If you don’t want to wait until then – here’s the new version of the theme’s functions.php with the Customizer bug fix (link); download the archive, unzip it, and upload the resulting php file into the theme directory in your WP instance (/wp-content/themes/Origami/).
