I am using version 1.9 spigot.
I get an error to the console when using the /wand command and opening the plug-in.

Note: I used the /wand command on the last line.

Looks like a config problem, have you customized configs?

I didn't customize the configurations. But I tried versions of spigot 1.9 1.10 1.12 1.13 but it still fails.

And you are sure you're using the correct Magic version for your spigot version? There is a version list here, if you are on 1.9 for some reason (not 1.9.3) you can't be using the latest plugin version.

I installed magic (6.0.4) and got the error again: latest.log

I can't see that file, can you just use pastebin or hastebin or something that's not a rar'd download?

I just tried latest Magic on 1.9.4 and it works fine. Are you stuck on version 1.9 for some reason?

Try deleting all the files in plugins/Magic, it really looks like you messed with the configs somehow.

I meant to note that if you can use 1.9.4 or above you can use the latest Magic. I'll try to test 6.0.4 on 1.9 when I get a chance.

Updated their comment with a proper link.

It has some errors because of it being an outdated version:

java.lang.IllegalArgumentException: No enum constant org.bukkit.entity.EntityType.VİLLAGER
java.lang.IllegalArgumentException: No enum constant org.bukkit.attribute.Attribute.GENERİC_KNOCKBACK_RESİSTANCE

Then again, those errors don't really make sense considering GENERIC_KNOCKBACK_RESISTANCE was introduced at the same time as the enum it is in. (Bukkit commit a5be7e19c2d5ba08d2df9f1190990b826e197f63)

I found spigot 1.9, downloaded magic 6.0.4 and I have no errors.

If you've tried deleting plugins/Magic and starting fresh, then I don't know what to tell you at this point, sorry.
