Same problem happens to me. Clicking on "Register" link in navigation results in error message "Error
Converting circular structure to JSON". Using latest from github

It works for me on latest. Maybe try to clear your cache.

AFAIK admins can see deleted topics and posts. If you log out, you shouldn't see it.

Small request for improvement: in library.js you have the hardcoded link http://platform.twitter.com/widgets.js . This gives problems (or warnings) with forums that run using "HTTPS". Can you modify the link to //platform.twitter.com/widgets.js? That way the browser will automatically choose HTTP or HTTPS depending on which protocol was used for loading the page :). Thanks!

Fixed

@Fayez-Abu-Helow No, it should work after enabling it in admin panel. If you are using NodeBB 0.4.0, which was released yesterday, maybe these plugins are not compatible with it, but I can't test it myself right now so I can't tell you.

You need to restart your forum after installing plugin

@planner
Hm, Are you really running latest version? It should be 0.0.4. Because I have exactly same plugin installed here http://manutdforums.com it is working for me, can you check if it is working for you too?
Edit: Try reinstalling plugin completely with npm remove nodebb-plugin-google-adsense and then npm install nodebb-plugin-google-adsense

@planner Did you try to clear your cache?

Nice work @dove totally destroyed my original plugin but this is good, one less plugin for me to have to update for 0.4x

I think a lot of people would find this useful. Thanks!

Haha, I saw your plugin, but I also saw this message "This plugin has been superceded by NodeBB's Widgets System, available as of v0.4.x.", so I thought that your probably won't update it any more
