Login: captcha always wrong + Blocking

Hi,

Is the 2nd time this week I do login and the captcha says constantly that the answer is wrong. I’m not so bad at maths to fail a question like 20+11.

After some fails, the login panel blocks my IP. Last time I tried changing my password, but I didn’t worked. So I decided remove the plugin folder on wp-content/plugins to login on the default URL (wp-login.php).

But, even I always check the “Remember my login” checkbox, today I’ve to do login again (and again, and again: the “Remember me” at login NEVER works).

So I’m being a bit tired of this plugin because is getting a great headache instead a helping guy. I searched for another people having the same issue:

I don’t use cache plugins, but I’m using the cache system of my hosting (Siteground). After cleaning the 3 cache layers (static, dynamic and memcached), the issue doesn’t fix and I still cannot do login on my WP without removing the plugin via FTP.

Thanks for helping.

Chris.
