Hello, i have installed the revive ad server few months ago and everything worked as it should until a few days ago. Even though no one touched any files or folders, banners stopped showing up and HTTP error 500 is reported when banners are supposed to load. "GET /www/delivery/afr.php?zoneid=9&cb=72142 HTTP/1.1" 500 Can you help me with this one? Edit: I have found the problem. HDD got full (due to the other site on the server) and one cache file was partially written. After i have cleared the cache, everything is working as expected.
