I’m getting this error: The site reports “Authentication error. Please deactivate and activate plugin” After running the tracker. I’ve reactivated many times but no difference.
There can be several reasons to get this error:
1) you do not have Google Analytics Account;
To solve this problem create Google Analytics Account.
2) Perhaps you have some kind of security plug-in installed or your host does not allow connection.
To solve this problem, please, contact your webhosting administrator and ask them to allow incoming and outgoing connections to the server secure.wpadm.com
