captcha doesn't render

successfully installed and worked made a mistake by enabling captcha functionality and it doesn't render the captcha image, any ideas?

whats happens if you goto http://www.yourstore.com/CaptchaImage.aspx?

might be a permissions error.

i have sum problem 1.40

"whats happens if you goto http://www.yourstore.com/CaptchaImage.aspx?"
This store is currently closed.
Please check back in a little while.

tried to change in DB

Common.StoreClosed to False
Common.LoginCaptchaImageEnabled to False
Common.RegisterCaptchaImageEnabled to False

not help
Store Closed and Captcha ON

Experiencing the same issue in v1.40:

I am developing on the local host and also set Captcha enabled on a virgin installation (it previously worked in 1.20)!.
Tried to go to URL ..\CaptchaImage.aspx as suggested above but reverts back to Login.aspx. - no fix
Captcha image is replaced by the word captcha
Tried to modify the SQL database
Table [Nop_Setting]
Common.LoginCaptchaImageEnabled = False
Common.RegisterCaptchaImageEnabled = False
Customer.RegistrationEmailValidation = False

Cache.LocaleStringResourceManager.CacheEnabled = false
Cache.CustomerManager.CacheEnabled = false

I did find that when I changed the following code to disable the cache, and then re-running the code I did remove the captcha problem on login.aspx,

SettingManager.cs
public static bool CacheEnabled
        {
            get
            {
                return false;
                //return true; ### changed as Captcha not working, return to true after one execution ###
            }
        }


Now shutdown,

Set the above code back to return True


And login!
I did find that the [dbo.Nop_Customer] database did clear my username which prevented me from logging in.
once that was fixed I am now back into my site as administrator!

(I dont knoww what other ramifications disabling the cache can do? can someone else explain.....








Note: Be very careful setting Common.StoreClosed = True, as you won't even be able to log into the site to do any admin!
