I am getting an error when I access the Campaign Linked Zones page:
Fatal error: Call to undefined method OA_Central_Common::OA_Central_Common() in /usr/home/paul/TL6/AdServer/OpenX/lib/OA/Central/AdNetworks.php on line 49
I seem to be missing the PHP OA_Central_Common class. What is that and where do I get it?
Thanks,
Paul.
