Tumblr Theme Reset Glitch
Keep an eye on your blog theme. Tumblr has a recent glitch where some blog themes and theme settings are resetting to their defaults. If this bug strikes your blog, try recovering your custom theme to its latest backup.
From the “Recover Custom Theme” page, choose your blog from the drop-down menu (if needed). Click the “View backups” button. Revert to the latest theme backup then check your blog theme.
If the reversion doesn’t work, seek a cached copy of your blog and check the HTML source to manually restore your theme.
