"Manage email reports - loading data..." is forever

I faced with the problem of subject.

My Piwik version is 1.8.3.
I’m running PHP 5.1.6 at the hosting company.

I tried to do the following with reference to the forum of piwik.

  1. I changed from “memory_limit=128M” to “memory_limit=512M” in php.ini.
  2. I could receive email without any problems for the correct SMTP server settings.

But it didn’t change.
So I checked error log of apache, I found an error log like the following.

PHP Fatal error: Call to undefined function filter_var() in /var/www/html/piwik/plugins/PDFReports/PDFReports.php on line 139,

PDFReports.php on line 139 shows

139 filter_var(
140 $parameters[self::EMAIL_ME_PARAMETER],
142 );

Please tell me how to resolution “PDFReports.php on line 139”.

Thanks for the report. The bug was fixed in SVN: http://dev.piwik.org/trac/changeset/6893
