If you create a post and publish it on your website, yet the post’s content does not appear, here’s what you can do.
First, ensure you have the Elementor plugin and the Royal Elementor Addon plugin installed and activated.
Next, create the post. Add title and content. Publish it.
Now, go to the page template section at the bottom-right corner, and change the template type to Elementor Canvas.
Now Save the update.
Next, edit the same post with Elementor by clicking the Edit with Elementor Button.
Commit an edit by probably changing the last character and inputting it back.
Save the update.
That is all. Now your page content should display at the front end.
Moving forward, keep editing the post with Elementor. Save and ensure the save is completed.
