I am getting redirected to home page when creating or editing post in wordpress. When I click on publish button it always redirects to home page and post is not created. 

```html
<hr>
  <p>some text.</p>
<hr>

<h2>Heading</h2>

<p>test para 1 - </p>

<p>test para 2 Go to - <strong>Setting</strong> </p>
<p>test para 3 - </p>
```

I am not able to save this post but if I post simple text without html tags it saves properly.
