LandClaiming plugin not working

So, basically, I have a lot of plugins, and normally don't have an issue like this, but when I get the 1.7.9 version of LandClaiming, it won't work. This is mostly because of the fact that someone decided to add Acacia Doors to the 1.7.9 version. I don't really understand why.

At least, that's what I found in the log.
