Bukkit

What steps will reproduce the problem?
1. When you click on some string to sort the items on the web

What is the expected output? What do you see instead?
I'm expecting same output - translated string, but when i clicked on anything (for sorting) it turns back to the English language..
You can try it on www.sh.4fan.cz/stats (where i'm testing it) - when you clicked on "Typ bloku" (what is Block Type in EN lang) - it will turn into "Block Type" ..

What version of the product are you using?
Statistics v.1.2.3

Do you have an error log of what happened? (Portal: check cache/error.txt)
Nope.

Please provide any additional information below. (Plugin/Portal Version, Server Version, PHP Version. MySQL Version)
Probably isn't important, i didn't have so many information..
But the Plugin version is 1.2.3, server is 1.7.10 (Spigot, you can connect with 1.8 and 1.7.X).. But that's not important - the issue is on the website.. PHP - 5.4.19
