I experienced the same thing. I suspect it may be an issue with authenticating with Google Analytics.
Check your GA account.
After some code analysis and experimentation, I found that I could get my settings page back by going to the database wp_options table and setting “ga_disable_gasites” to “enabled”.
I’m hoping this will be only a temporary workaround. According to my brief look at the code, having that option “disabled” is for sites that may connect to more than one GA account. And this is not the case with my particular site.
But, the code that tries to fetch the multiple-account information, also tries to successfully connect to Google. Apparently it cannot and returns a False value which cannot be enumerated with ForEach — and the plugin simply dies right there.
So I say again, check your Google Analytics account.
