I had piwik 1.1 working fine for over a year on my Windows Server 2008 R2 VPS.
php version 5.2.11
I got the piwik email “Piwik 2.0 - Monumental Release - Why you should use it in 2014!” and decided to upgrade using the “one click” option. All seemed to go well except for a prompt to delete the libs/smarty directory…but then 500 server error and localhosty/piwik is totally unavailable.
Like an idiot I trusted the “one click” upgrade and didn’t back up first (i know … I know…)
Now my piwik is dead in the water. Any assistance/suggestions would be most welcome.
