Blank page when selecting "Posts" or "plugins"

Please help, my site is still live on the web and works perfectly but I am getting a blank page when I select “posts” “all posts” “installed plugins” “appearance” and “themes” from the side panel in the admin menu. I have tried repairing the database, renaming the plugins folder to remove them and also changing the theme folder to remove the theme but nothing is working. At one stage nothing was working but I removed a plugin called “wp seo automation” and since I removed that everything started working again apart from the stuff I have just mentioned!. As an example I click on the “Posts” tab and by browser goes to “https://mywebsite/wp-admin/edit.php” but I just get a blank screen! But if I go via a different route “https://mywebsite/wp-admin/edit.php?post_type=post” then it loads the page and I get to see all my posts!. Please can someone help.

Thank you
