HI, what version of DNN and DF are you using? Also, can you check the following:
1) in your web.config, you have set this:
2) in your Captcha field, be sure to click on "Enable Captcha Refresh" and "Enable Captcha Sound"
I just want this verified first. If possible, can you duplicate this on www.betasprings.com (username: host, password: dnnhost).
I did Advanced Captcha on my localsystem with DNN 5.1.0 and DF 3.0.10 and it was displaying fine. -- David
