Invalid argument supplied for foreach() in .../plugins/Referrers/SearchEngine.php

Support & Bugs

Hi,

Since the last update, I get a lot of such errors:

Invalid argument supplied for foreach() in …/plugins/Referrers/SearchEngine.php on lines 219, 220, and 271.

Why would this be?

Thank you

Could you maybe try to clear the cache (tmp/*)?

Thank you. I just did it although it was not possible to really have it deleted per se as Piwik, being active, keeps recreating folders and files.
I’ll see what happens…

Thanks
