Didn't get your last reply about cron.

Just contact your hosting company and ask them to enable PDO for your account.

Now I got the email notification correctly from the site activity.
its only happan when i open the URL mysite.com/ow_cron/run.php

My Qustions is
Email notification is running correctly (yes)
URL mysite.com/ow_cron/run.php (error)

To make sure Is it Normal?

Thank U
I will ask my hosting about PDO...

Try enabling debug mode and open the run.php in URL one more time. That would display the initial error to you.

Enabling Debug mode
Opening the URL mysite.com/ow_cron/run.php

Try disabling the Guests plugin and see if it helps. If it does, try reinstalling the plugin.

Hi Michael,

I've got the same problem as cit24. The error was gone with the Guests plugin disabled, but it returned after deinstalling, deleting the directory from the server and reinstalling. Have you got another idea?

best regrads,
Oliver

Oliver, I believe that your question should be answered by the developer of Guests plugin that you use. As you said, when plugin is disabled, error disappears. So the problem lays within the plugin.
