[Piwik 2.0-b7] TCPDF ERROR on ARCHIVE.PHP


#1

Hi,

We are currently using version 2.0-b7 of Piwik due to previous errors on TCPDF when downloading PDF reports.
The said version fixed the error.

Now we have a new problem when we added a cronjob for archive.php.
Please advise.

Here is the error :

Error in the last Piwik archive.php run:

First error was: Got invalid response from API request: http://www.example.com/piwik/index.php?module=API&method=CoreAdminHome.runScheduledTasks&format=csv&convertToUnicode=0&token_auth=c18d4868d17cba5fff7b50b0473257f7&trigger=archivephp. Response was '


There is an error. Please report the message (Piwik 2.0-b7)
and full backtrace in the Piwik forums (please do a Search first as it might have been reported already!).

(Matthieu Aubry) #2

This bug is fixed in the latest 2.0-beta11. thanks for the report!

Hi Matt,

After updating Piwik to the latest release candidate of Version 2.0, we are still receiving the errors above. Archive.php runs every hour on cron. I think it has a conflict with the script that sends out the PDF reports which we run 3 times a day at per hour interval.

Thanks!


#4

Hi Matt,

I think the problem with TCPDF is on the SVG logo of Piwik.
Please see attached screenshot from the PDF report output.

Thanks!


(Matthieu Aubry) #5

PDF is trying to load the PNG logo not SVG.

Can you try to disable the Theme Morpheus, use Zeitgeist, and see if the PDF start working again?


#6

Hi Matt,

Thanks for the advise. Archive.php cronjob does not return any error anymore when we switch to Zeitgeist.

We have also changed the default logo of Piwik to our own logo.
Problem is, it does not appear on the PDF reports. It only works in the Piwik website.

Thanks!
