This plugin is no longer maintaned.
Both of the available GA plugins appear to be broken and there is no sign they will be fixed any time soon. The most commonly used one does not appear to work in 3.2.0 beta at all. The other one (d51) doesn't work at all unless you first rename the file and even then is missing the quotations around the GA user ID number in the script so it will appear to work but you will get no statistics. This plug-in is a fix to the d51 plugin code and it should work with all 2.x and 3.x versions of b2evo without trouble. Please let me know if you find a problem. I will also consider feature requests, time permitting. Original credit for the code goes to Travis Swicegood
