Using a Captcha generally prevents spam from automated bots but sometime they can manage to crack the captcha, you might try using a different one such as Recaptcha. But also consider that the spam may be entered by real people and a captcha will not prevent that.

Hope that helps,

If you have the captcha enabled on the login page and that is preventing you from logging in then you would have to update the database:

UPDATE mp_SiteSettingsEx
SET KeyValue = 'False'
WHERE KeyName = 'RequireCaptchaOnLogin'

then you would need to touch Web.config file or recycle the app pool to clear the SiteSettings from cache

Hope that helps,

I don't understand your question. The sql I provided was to change your site so it doesn't require captcha for login so you could login again. You don't need to use sql for anything else. You can specify the racaptcha keys from the Site Settings page. Just make sure you put them in correctly.

Hope that helps,

No, that key is a true or false about whether a captcha is required on the login page. The setting for which kind of captcha is used is in a different table and field, it is best updated from the web ui in Site Settings not by directly accessing the database. I mean it could be updated by a query but it would be a different query and there is no reason to do it that way once you can login it is far easier to do it from the UI.

Best,

Joe
