I've tried installing OpenAds latest stable release (2.0.11) and it works great until I log out of the ACP. It won't let me back in. I'm not having much luck getting support to overcome this problem, so I may need to find something else to do the job. Is there another ad management script out there with similar functionality to phpAdsNew/OpenAds?
double check your mysql database.. whether your admin user/pass is correct.. openads is definitely the choice for most.
Mxhub, I've checked it. Did you read the thread I linked? It's a bizarre situation. It lets me log in one time and one time only. If I can't rely on access to the ACP, I really can't use it. OMI, I'm not limiting myself to free scripts. If you know of something comparable, please share. I need to get a solution implemented soon.
Hotscripts uses adjuggler.com, but I've never used it personally, so I can't give an opinion about it, but they rotate thousands of ads across their network, so I assume it's good. revsense.com might work for you, although I don't know your budget. Maybe look through the other scripts on HS. http://www.hotscripts.com/PHP/Scripts_and_Programs/Ad_Management/index.html
