What Piwik and PHP versions?

3

PHP Version 5.2.8 / FastCGI / Windows IIS 6
Piwik Version 1.5

4

Sorry, I’m unable to reproduce this on my Linux devbox, and the oldest php version I have on Windows IIS is 5.2.14.

Please try updating to a newer PHP version. I’m guessing it’s a winphp bug.

Looking at the Zend Framework code, it shouldn’t fail like that because _writers is a protected data member – hence visible to its subclasses – yet isn’t redeclared anywhere.

Can you use the latest files in:

See if that changes anything.

I’ve modified the files to the ones that Anthon posted.

Yielded the following results:

core/Piwik/Session/SaveHandler/DbTable.php is a new file. Use the nightly build at http://qa.piwik.org:8080/nightly/

Anton,

Changed the files to the nightly. Was able to get past the login screen, but takes several minutes to return the dashboard page, and all other pages.

On the dashboard page there are no websites listed.

Any further ideas?

9

We expect a delay on the initial signin because Piwik is re-merging/minifying static assets (javascript and css). But several minutes and delays on other pages is unusual. Can you check the web server logs? It sounds like the minification is not completing.
