I haven't made any changes to my sites in many years. I'm running a number of old scripts that are no longer supported, including a self-hosted script of OpenAds/OpenX to manage an inventory of banner ads that display on my sites. I'm thinking about making some changes to my sites (including upgrading the php version on the server which will likely break the old version of the OpenAds/openX script that I'm currently using), but I'm not current on what solutions are out there, so I thought I'd ask here what you all are using.
