cant exclude some users by id

What version of the plugin are you using? This is a known bug that should be fixed in the latest version (1.7.1).

1.5.1 version. Ah isee then i should update plugin then. Sad i changed few tags in log and ladder page. Also css how to modify them again :(. Forgot wich files i changed. File name for log and ladder ? Can you tell please

I think the files you are looking for are:

components/points/includes/logs.php
components/points/includes/functions.php

The ladder has been moved to components/points/includes/points.php in the most recent version, though.

This is why it is usually advised not to edit a plugin directly. You could instead request for some changes to be made. In some cases it might be better to copy the part of the code you want to change into a custom plugin, and then modify that copy.

Ok i remade changes. Cant find translation for. Weeks ago months ago in po file

Those strings might be from WordPress and not from this plugin.

I think maybe the plugin didn’t upgrade properly. You should try reinstalling it from a fresh download.
