After upgrading to v1.7 i had to edit libs/Zend/Session.php.
Line 28:
// require_once ‘Zend/Session/Abstract.php’;
Line 38:
// require_once ‘Zend/Session/SaveHandler/Interface.php’;
My first thought was your Zend installation interferes with our Zend installation so i updated to 1.11.11 as “libs/Zend/Version.php” shows.
No difference.
I had to comment in both lines.
Another file was “core/DataFiles/Currencies.php”:
Line 19:
if (!isset($GLOBALS[‘Piwik_CurrencyList’]))
Somehow this doesn’t work and i had to change it to if(empty(…)).
I cleared the cache and assets before as some other posts suggested.
