I am using PIWIK 2.8.3 with PHP version 5.3.3-7+squeeze22.
When I click on “Settings” (more precisely, this URL: …/piwik/index.php?module=UsersManager&action=userSettings&idSite=1&period=day&date=today), only a blank page is shown. (This happens on Chrome; when I use IE, a HTTP 500 error is shown.)
I am not good with PHP, but I traced the problem back to a function “getMenu()”. It is called at several places, for example in “setBasicVariablesAdminView” of ControllerAdmin.php, and anytime it is called, the program gets caught in some kind of infinity loop and never gets back.
I was not able to find the implementation of that function (or rather I found many implementations and couldn’t figure out the right one), so my debugging process stopped here.
Thanks and best regards
PS. The “Marketplace” doesn’t work either showing the same symptoms. Didn’t try to debug here so far.
