[Query loop] Wrong number of posts is displayed when Posts per page don't have a value

[quantumleap33]

I was under the impression that this issue was fixed.

Description

The wrong number of posts is displayed when Posts per page don't have a value.

Steps to reproduce

1. Insert a query loop and don't enter a value in the Posts per page field. Values seem to default to 10.
2. View loop in the front end

Expected behavior

All posts should be displayed.

Actual behavior

10 posts are only displayed in the front end. The value of 10 is set and is not even related to the Settings -> readding -> Blog pages show at most value in the blog settings.

@quantumleap33 if you would like to display all your posts you can use -1

@JeanPaiva two issues:

1. It's not obvious to users.
2. It doesn't work on the backend edit screen.

We can resolve the issue by not allowing the this field to be left empty.
