Sometimes, when there are not enough posts, the select box can misbehave. Try setting it explicitly to the “Hello World” post. Then click the dropdown again and set it to “Wedding Dresses”. Let me know how it goes.
Also, please make sure that the Trash is empty because you may have deleted the default sample post, but it can still be pulled up.
Thanks – emptying the hello world post out of trash seems to have sorted the problem. If I might just ask another question. Is it possible for me to disable the blog feed – I can’t find a way of doing it.
You’re welcome!
When you say “disable the blog feed”, you want to remove that section altogether and not show any recent posts on the home page?
If so – please create a new page (for example “Home”). Now go to Settings > Reading and set this page as the front page. See this for more information. Once this static page is set up, you will no longer see the recent posts on your home page. However, you’ll be seeing the title of the page “Home” which you can hide by using this custom CSS in Appearance > Customize > Additional CSS:
.home .entry-page h1.entry-title { display: none; }
Hope that helps!
