Hello! I love this plugin. However, since I installed it, I cannot use /trigger for anything. When I use it, it says:
You cannot trigger this objective yet.

Any ideas?
Thanks.

There is probably a permission behind the command. Have a look at using the verbose feature to determine if there are any required permissions you need to add.

I already have all the permissions added and minecraft.commands.trigger

I don't think /trigger is a minecraft command as I can't remember any command like that.
So you should double-check that you have the right permission (Use Verbose like Omega suggested) for the command.
Maybe LP is in conflict with another plugin? A common mistake people make is to not remove the old permission plugin, if they switch/migrate from it (f.e. from PEX)

I removed PEX after migrating

/trigger triggers a scoreboard objective. It's used in datapacks.

Did you use verbose?

Yup

Everything is true

List of plugins

Does /minecraft:trigger work?

Nope
Same message

Same deal in verbose? Can you actually show us some output?

Please do /lp verbose record, type the command, /lp verbose paste then send the link here.

Keep in mind that the score needs to be allowed to be triggered beforehand. And that every time

@Turbotailz Ok! Let me try

Here

@BrainStone Yes, I enabled all the scoreboard objectives

Maybe you need to be opped?

The thing is the permission check succeeds. So I don't see anything on the LP side that's going wrong here.
Sadly vanilla commands are handled very wonkily on Spigot. Maybe try reaching out to their support.

The permission check may be succeeding, but the code might be checking for op too.

@lucko I have op

@BrainStone thanks for the suggestion.
Where can I find that?

Spigot has a JIRA bug tracker available from their website under "Hub".
