Since the update to 2.5.3 I'm again getting the error message:
"Akismet has detected a problem. A server or network problem prevented Akismet from checking 1 comment. It has been temporarily held for moderation and will be automatically re-checked in 5 minutes."
Whenever I view comments. This first started happening with 2.5.0 but was resolved in 2.5.1. The fix seems to have gotten lost in 2.5.3.
If I click the "Check for spam" button the spam comment gets deleted but the message is not cleared.
