I found in the documentation that I can achieve this with the field=slug attribute.
Hi Ben, I still haven’t seen anything to resolve this yet, have you had a chance to login and see what is happening?
I left it at the default, then I deleted all the text in there and try to save settings again but it still comes up with Failed security check. Can I PM you login details so you can check for yourself?
I see this error after I try to save the add-ons settings, in the settings section of the plugin.
