It' a "Undefined offset: 1" error on lines 138 and 141. Check my error log for more details.
I do know that Akismet was updated about 2 days ago for WordPress because I own 2 WP sites. I assume that their APi's may have been updated.
Alright I will look into it later today.
For now you can disable the Akismet protection until I release a fix for it.
Thanks for the report.
No problem. :)
