OSQA-516, bugfix for the Akismet Module. There was problem with the loading of the ReCaptcha settings if the ReCaptcha module has been disabled. Now we added a try-except block that fixes the problem. Some improvements made. Better found-spam message: now we hide the Submit button of the found-spam message in case there is no recaptcha field -- we just don't need it. fields={} has been added to the SimpleCaptchaForm. It fixes the error @Nigel mentioned about.
