Hi all, I have used these plugins together on countless sites and never have had this issue. After searching the forum it appears no one else has either so here it goes:
After activating Really Simple Captcha and after clicking add "Captcha" field, it does not add the new field or do anything else, and I get the following console error: http://cl.ly/Pzjp
Deactivating Really Simple Captcha makes it work properly again.
Running latest version of both wordpress and both plugins.
Any help is greatly appreciated.
