Feel sure I've done this before but can anyone advise if it's possible to see logs from email capture plugins and if so, where? Thanks.

id guess plug-in implementation

Thanks. I had to kill my existing plugin and create a new one, something odd had happened there was no plugin to look at for some reason even though it appeared in manage plugins. Not only that but the first implementation didn't even accept emails and just died despite the same js file being used. (sorry that all sounds cryptic kinda hard to explain!)
