Upon installing and running the language setup, I received an "out of memory" error (stuck at about 32mb). I've run this plugin on other installs and it works, but I'm wondering why it's not working now.
With this plugin installed, I also received an "out of memory" error on at least the following admin pages:
add new page
add new post
Unique to this install?
WordPress is installed in a different directory, new theme (I'll test later...)
