I've been disappointed and frustrated with FSCF ever since I discovered that vCita is all over my database in the form of transient files, which is odd since I do not want or use it and have it UNchecked in all of my forms.
One of its files in the wp_options table of the database was a very long base64 string that should be against the rules for clean WP coding. When partially decoded, it appeared to be in Russian! I deleted it.
Now the forms are not working because it won't recognize the corectly-entered Captcha code. It appears as if vCita is tightly integrated with the Captcha and is blocked if the vCita folder is altered. : (
The creator of the form is making money by partnering with vCita, but he is harming his reputation and angering a lot of users that trusted his plugin. It seems that the only way to get rid of vCita is to get rid of an otherwise excellent plugin and find a replacement.
