Same problem for me. I have made all the modifications on the session.php files but nothing new :
Fatal error: Exception thrown without a stack frame in Unknown on line 0
I have read the ticket #2491. I have the piwik_session table so I think no problem with the DB update. Nothing in the error logs except the fata error.
Just one message to inform that I finally updated my php 5.2.6 to 5.3.2 to resolve the problem. So if you have this possibility, it’s most simple, no fix at this date works for php < 5.3.
Ferment : still unable to access piwik after applying your solution : but I do not have zend error (well that 's what I guess so far) : My error is as reported above : Fatal error: Exception thrown without a stack frame in Unknown on line 0
In my case, my vanilla php builds of 5.1.3, 5.1.6, 5.2.0, 5.2.1, 5.2.6, 5.2.10, etc don’t exhibit the problem.
However, upgrading to 5.2.11 (or later 5.2.x) or 5.3.4 (or later 5.3.x) should fix the problem for users who have the trunk patches, yet are still affected.
is there now something to solve the problem? I have 5.217 php and the error Unable to start session.
Fatal error: Exception thrown without a stack frame in Unknown on line 0
I can´t update php and the above help with the temporary workaround does not work…
any ideas?
thx
Cyberurmel, please update your ErrorHandler.php (core/ErrorHandler.php) with the new Version from trunk. Then you should see a more descriptive error message and we can tackle the root cause of the problem.
thx., i load from http://dev.piwik.org/trac/browser/trunk/core/ErrorHandler.php and update it in /core/ but nothing changes if i reload the login site?
