I would need some help from the community. For a multi-author blog with authors that have little knowledge of WordPress, I would like to change the number of posts displayed in the admin back-end from the default (20) to 100.
I would like to accomplish this through the functions.php but don't know where to start...
This value should override the default 20. If a user chooses to manually set this value to anything different than 100, it should override that choice and set it to 100 regardless of user choice (I am actually hiding the screen options button for my contributors so this shouldn't be an issue anyway).
Is this possible and could you point me into the right direction please?
