Cannot upload more than 20 images with WP Users Upload Pro

Your server (PHP) has a setting to control maximum number of files when uploading. By default, it is 20. So in many cases, you can only upload 20 images in a chapter with WP Users Upload Pro. To fix that, you need to change this value on your server.

You can use your hosting provider to do that for you if you are not familiar with server management. Or else, you can find php.ini setting file, change this value

 

max_file_uploads

 

Change to bigger value, for example 100

 

max_file_uploads=100;

 

Then save the file and restart your server.
