Silverstripe Translatable无法创建翻译

I'm currently using Silverstripe 3.4.1 with Silverstripe Translatable 2.2 (it's said to support SS 3.2+)

Everything shows up fine, except that the create button doesn't work at all:

Anyone has a similar issue or know what to do?

I found the problem

Silverstripe Translatable plugin folder has to be named "translatable" exactly
