thanks, but I don´t use BackupBuddy..
It seems that this captcha isn´t good to use with caching-tools like W3TC, so I erase it. To exclude any page for a captcha isn´t an option for me..
I´ve insert 3 own making Honeypot´s and one field that needs an exactly value. Description to this field is a little quiz like: Insert result of three plus 4 as a number. Here the user needs to input: 7
After create this fields, I connect the appearance of the input-button (inside the form-settings) with this fields. That means, if one of the Honeypot-fields (position: absolute; z-index: -5; and display:none; and visibility:hidden; - on this way they are not reachable for human customers) get any value, the Button disappear and the form can´t be sent. And if the other field get another value than 7, the button disappear, too.
That works pretty fine for me. Since 5 days no spam, one plugin fewer and it´s cacheable without any sort of issues.. If you get spam after a while on this way, just change the quiz..
Hope that helps you, too..
