Hi, I could not find the format tab in the add new posts section. It was not available to select.
First, visit the Screen Options hanging tab at the top right to make sure that the Post Formats feature is not simply disabled or hidden.
If you don’t see a Post Formats option in the Screen Options tab, then it’s likly your theme has disabled support for Post Formats.
As we mentioned in our video tutorial on Post Formats, theme developers may choose to enable or disable support for Post Formats. It’s possible that your theme doesn’t include support for specific Post Formats, or you may not see the Post Formats chooser at all.
If your theme does not support Post Formats, you’ll either want to find a different theme, or limit your posts to the default post format supported by your theme.
Hope this helps.
