AdvancedLogin/ImageChallenge.captcha.aspx  (Canada)
Hi,

 I am having issues with this 'AdvancedLogin/ImageChallenge.captcha.aspx' which is causing my DNN instance to error. I am not sure what to think of this as it does not seem to be a failed captcha input since I have tested that scenario but whatever it is it eventually leads to a memory run-up on our server and an subsequent reset of the app pool
Here is the error

Re: AdvancedLogin/ImageChallenge.captcha.aspx  (Australia)
We are using the built in DNN Captcha control.

There have been versions of DNN that have issues with this control. There is a post here about it: http://www.dotnetnuke.com/Community/F...

Please We cannot fault it on DNN 4.9.5 or DNN 5.6.0 and would always recommend that you run DNN 4.9.5 or the latest stable release of DNN 5x.

Are we guessing correctly that you are not on one of these versions?

We have since also implemented some Google recaptcha as an option.
