I would also like to know the “Error unserializing the following response from…” error means. The message from the API is “Purging temporary archives: skipped”, which doesn’t seem like an error at all. But the fact that the archive script reports an error unserializing that message from the API makes me wonder what’s going on here.
Could someone please confirm whether this is anything to worry about, and whether we can safely ignore this message by commenting out the [log] section in config.ini.php?
I still receive cron errors like this with 2.1.0 (but this is maybe unrelated?):
PHP Warning: filemtime(): stat failed for /var/www/path/piwik/tmp/climulti/f77cc04928ddba15b9805460ccb4ed4d239616bd4577c7ff8b7656da4afa47dbaa766b4c43d4205b4f99d72a4640a1636aa50.output in /var/www/path/piwik/core/CliMulti.php on line 184
PHP Warning: unlink(/var/www/path/piwik/tmp/climulti/f77cc04928ddba15b9805460ccb4ed4d239616bd4577c7ff8b7656da4afa47dbaa766b4c43d4205b4f99d72a4640a1636aa50.output): No such file or directory in /var/www/owncloud/piwik/core/CliMulti.php on line 187
But now I have upgraded from Piwik 2.1.0 to Piwik 2.3.0 so lets wait for results
although I have run: chmod -R 775 /var/www/path/piwik/tmp
I still have similar problem with 2.3.0 :
PHP Warning: file_put_contents(/var/www/path/piwik/tmp/climulti/archive.sharedsiteids.pid): failed to open stream: Permission denied in /var/www/path/piwik/core/CliMulti/Process.php on line 140
Each hour (cron runs hourly) I still get the same warning:
PHP Warning: file_put_contents(/var/www/path/piwik/tmp/climulti/archive.sharedsiteids.pid): failed to open stream: Permission denied in /var/www/path/piwik/core/CliMulti/Process.php on line 140
After you get this message, do you see a file /var/www/path/piwik/tmp/climulti/archive.sharedsiteids.pid in your server? which permission has this file got?
