Sometimes you may want to edit all the posts at once, like changing the author name or changing the category name and then publish or update it. To edit multiple wordpress posts at once, follow the below steps
Step 1: Select the posts you want to edit
Step 2: Then select “Edit” and click on “Apply”
Step 3: Then select the options you want to change (In this case I am changing the status to Published) and then click on “Update” button
Step 4: As soon as you click on “Update” the posts will be updated
