I see someone else here saying they are having problems with Analytics. I tried to do a Fetch as Google in Webmaster Tools on a new site, and got an error message. Returning a HTTP/1.1.418. All pages that had been indexed are now deindexed. Not good!!
Contacted my host and they said it was this plugin. Of course I had deactivated all plugins EXCEPT this one while trying to find the problem. They suggested trying to whitelist Google bot but I see no way of doing that. Deactivated the plugin, tried fetch as google and it worked.
The weird thing is I use this plugin on multiple sites. I've only checked one other - I'll be checking them all! - and Google is able to access that site. For the most part, I install all the same plugins on each site I set up.
So a few things. WHY is this blocking Google and is there a way to whitelist Google if there is a problem?
Oh, and one more thing. It appears that once you've enabled the banned default blacklist and added it, there is no way to disable this feature. That was the first thing I tried - before deactivating the plugin entirely - and once you disable the feature and save, it just shows as enabled again. I've tried this on my test site as well, and the same thing. No way to disable feature once enable.
