Hello, I have been having a problem with BattleKits recently. Every time I do a command by battlekits, it says:

An internal error occurred while attempting to form this command

I know the problem, well a little part of it. Whenever I reset my kit config, everything works fine. So I know I did something wrong with my kit config.

Here is my kit config: http://pastebin.com/kF19ecsR

Does anybody know how to fix this?

Just from taking a quick glance at your config, I noticed that you haven't wrapped slot 0 in the archer kit and the knight kit in single quotes.

Change that and re-test, then let me know your results!

Not following #1

np98765, I have fixed the issue that you noticed, and completely restarted the server. It appears that there is still an internal error when I try performing the commands. I will continue my search for the problem.

What's the new error in the console?

Those are some errors & stuff in the console that I found when trying the command /bk, /kits, etc.

You cannot do this:

(Use double quotes for the outside, and signle or the inside.)

(The right-hand-side must be wrapped in single quotes)

(Same problem)

Potential issues:
Ideally all text should be wrapped in single quotes, e.g.

Should be:

Once you think you've fixed these issues, use this tool to check your config file (just paste it in).

Alright, thank you guys SO much! I have fixed it, and I found another problem that wasn't detected:

When I named the bow in the archer kit as: '&cArcher's Bow', I realized that I couldn't have the ', because it ruins the coding, and thinks you're trying to do something else, other than naming something.

Good catch, yeah. You'll need to escape single quotes with a backslash,

'Archer's Bow'

Seems all sorted.
