Scheduled Reports not sent - missing Zend_Loader - Piwik v 3.0.1

I am getting the following error from Piwik when trying to send a report via e-mail.

[Fri Feb 03 01:01:01.806263 2017] [:error] [pid 4709] [client] PHP Fatal error: Class ‘Zend_Loader’ not found in /var/www/html/piwik/libs/Zend/Mail/Transport/Smtp.php on line 197, referer: http://localhost/piwik/index.php?module=ScheduledReports&action=index&idSite=1&period=day&date=2017-01-30

This comes from the Apache error.log file. I am running Piwik in CentOS7, with PHP 5.6.9.
Any ideas why for SMTP Zend_Loader is not found? Or is it the class that is being loaded by Zend that is not found?

Thank you in advanced for your help.

I don’t know if your problem is the same as mine, see:

Best regards,

Doesn’t look to me as if it is the same. Yours sounds like a problem with the database.

Too bad. Let’s hope Piwik can help both of us.
All the best,

Had that error also. fixed by setting authentication method to login as discussed here How do I send Piwik emails using Gmail SMTP server? - Analytics Platform - Piwik . hope it helps.

Thanx for the tip! Will check it out. :grinning:
