[Plugin: Robots Meta] Authors redirected to homepage when trying to make a new post

when logged in as an author I am redirected from /wp-admin/edit.php to the site homepage when trying to make a new post.

When logged in as admin I am taken to the new posts page

So in summary, only admins can make new posts.

Could someone advise on a cure as my site is multi author with only myself with an admin account and I dont want to upset the authors.
