Do you have any idea what I can do to make it work?
Basic troubleshooting of addons.
Make sure you didn't end up with too many folders in addons. /addons/awarn(1)/awarn , where 1 would have no files in it but the additional awarn folder.
As for merging it with ULX folders, that alone can cause troubleshooting issues, as you end up with files scattered everywhere within ULX, and may be missing some.
Are you getting any errors on your server during startup related to the awarn folder?
Did you accidentally place it on your client folders instead of your server?
Too many other minor troubleshooting steps to list.
We know it works for majority, the issue is likely something simple on your end.
Can I give certain groups the permissions to use this? for e.g. Moderator
Use ulx groupallow to give any of the awarn commands you want your moderators to have.
There are several commands related to awarn. See the release first post to determine what you want moderators to have.
also is the plugin updated to 2.5 DarkRP?
No idea. We don't support or program compatibility with DarkRP.
It's compatible with versions of ULX as of this post.
