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.
- I changed from “memory_limit=128M” to “memory_limit=512M” in php.ini.
- 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
Please tell me how to resolution “PDFReports.php on line 139”.
