Problem with choosing primary category in blogpost

Hello,

I’m sorry to hear about the issue you’re facing with selecting a primary category in Rank Math after switching from Yoast. It seems like you are unable to see the dropdown menu for choosing the primary category when selecting more than one category in the editing mode of a post.

To fix this issue and be able to choose a primary category for your blog posts that fall under multiple categories, you can follow these steps:

1. Open the Post/Page/Product in your WordPress dashboard.
2. Choose more than one category from the list of available categories in the sidebar of your editing post screen.
3. For the Classic Editor, choose the Category radio button to set your primary category.
4. For the Block Editor, set your primary category from the drop-down list.

If you are still facing difficulties after following these steps, please feel free to reply to this ticket, and a human agent from our support team will assist you further.

Thank you for bringing this to our attention, and we appreciate your patience as we work to resolve this issue for you.

Best regards.

Let us know how it goes. Looking forward to helping you.

Thank you.

Hello,

We checked your website and found that you were using the plugin on Easy Mode and that’s why the Primary Taxonomy option was not showing on Titles & Meta.

However, we switched to the Advanced Mode and selected the Category for Primary Taxonomy. Now, the primary category drop-down option is appearing on your post editor page. Please check the screenshot in the sensitive data section for your reference.

Hope that helps and please don’t hesitate to let us know if you have any other questions.
 
Thank you.
