unclutter the posts page?

You have a couple of options:

1. Use Screen Options at the top of the page to uncheck which columns are displayed in the table (only affects currently logged in user)

2. Use the filter wpseo_use_page_analysis as explained in the API docs like this (should go inside your functions.php file):
add_filter( 'wpseo_use_page_analysis', '__return_false' );

3. Use a plugin like Codepress Admin Columns to show/hide specific columns on a variety of admin screens (love this plugin!)

P.S. This has already been dealt with multiple times in these forums, I know searching the forums isn’t fun– but sometimes it saves you time ??

Thank you Hassan for your kind reply:

1. I use wordpress for several sites since WP 1.5 and I was unaware of the screen option: it’s great, and I feel sooo dumb!

2. I will test the functions.php approach.

3. yesterday I tried the CAC plugin, it’s ok in most of my sites and has other interesting features.

PS: for reasons that may only originate from my own, I could not find a prompt reference to this issue.

Thank you again ??

You’re welcome.

About the Screen Options menu, believe it or not you’re not the only one. That’s why the core team is considering a fix for this. See the trac ticket.
