Openx Ad Delivery Issues

My System

• Apache 2.2.9
• PHP 5.2.9
• MySQL client version: 5.1.28-rc
• Openx v2.8.5

I am using the Javascript single page call to serve my ads. I am running an in house CMS where everything is processed through a template.php file.

My Issue The success of an ad being served seems to be very hit and miss. The placement or type of the ad does not seem to matter. For some reason, the loading of the ads is very spotty. Each page serves an average of 3 ads. Sometimes none show up, sometimes 2, sometimes 1. There does not seem to be any consistency in the problem occurring. The problem seems to have worsened since I updated to the most recent version and started using Single Page Call.

I have checked the source. All Javascript script is in place, but the ad cont开发者_C百科ent is not generated under the script where it should be. The space where the ad should be is just empty.

No Javascript errors are generated.

Any help will be greatly appreciated.

For me, this happened when the campaigns assigned to the zone were all contract and there was no Remnants assigned. OpenX basically had no banners with impressions left to display.

Also, another time t his happened was with their implementation of Single Page Call. OpenX pre-loads all zones you have put into the array on every page, regardless of if they are displayed or not. So if you have a lot of zones, the ones near the end of the array can not get any ads because the ones above it take all the ads with impressions.

If you have a CMS with a lot of advertising zones, you're going to have to dynamically control the Javascript array to only load the zones needed for display on that specific page. I have a solution for Joomla if you need more details.
