#1

Greetings,

After upgrading from Piwik 1.11 to 2.02 it completley stopped working:
Warning: register_shutdown_function(): Invalid shutdown callback ‘’ passed in /usr/www/users/medihi/medihimal/piwik/index.php on line 66

Backtrace -->

#0 Piwik\Error::errorHandler(…) called at [:]
#1 register_shutdown_function(…) called at [/usr/www/users/medihi/medihimal/piwik/index.php:66]

Hello

I have got exactly the same error message.

Though I updated form the latest version before 2.02.

Any help to get this solved?

We need very much our so loved Piwik dashboard.

What PHP version are you using?

#4

Using PHP 5.4.23 here

#6

You’re both using PHP 5.4.23 so maybe it’s a bug in this particular php version, can you try upgrade?

#7

upgrade sadly not, my provider (Hetzner) sadly just offers to downgrade it.

#8

Maybe downgrade to 5.3.x would work ?

#9

That worked. But i fear for those who cannot downgrade so easy without breaking the whole site.

#10

yes you’re absolutely right! I have created ticket at invalid shutdown callback when eAccelerator is enabled · Issue #4439 · matomo-org/matomo · GitHub

also proposed a fix at: Refs #4439 Registering the callback in the frontcontroller and using … · matomo-org/matomo@8318219 · GitHub

can you please try this fix with the previous php version that it was not working?

#11

Seems not to work, just getting a blank screen without output. I attched the 2 changed files as Rar archive. its not a pdf as it claims.

#12

The two correct files can be found here:

https://raw.github.com/piwik/piwik/master/core/FrontController.php
https://raw.github.com/piwik/piwik/master/index.php

Re: blank screen -> do you see an error in your server error log file ?

#13

ok updated with your files, the blank screen is gone now and he shows me a error. Now also the Login
window shows up.

Oh that is good that you are willing to help.

I am not so technically skilled but can tell you that we are hosted via HETZNER, too!

So, very likely the php version or Hetzner peculiarities are the source :frowning:

#15

Please post a comment in this ticket if you experience this bug with PHP 5.4.23 or with a different PHP version: invalid shutdown callback when eAccelerator is enabled · Issue #4439 · matomo-org/matomo · GitHub

Happy new year!

#16

I do not dare to update as long I do not know wheter the ne 2.03 works.

Can anyone tell me with Hetzner?
