I have the same problem. An authenticate() method is failing; ga_get_analytics_accounts() returns and sets $uids = false, and code tries to iterate over $uids.
The exception thrown in authenticate() mentions /etc/curl/curlCA CAPath.
I am running on a Solaris machine, is this a platform issue?
I don’t have a /etc/curl directory, but I’m also unfamiliar with the exception message, or curlCA
