Fix Video Monetization Platform

My video-sharing site was previously set up so that:
1) the main Siteingen engine ran smoothly,
2) ads played on every video, and
3) both the viewer and the uploader earned automatic credit when a video was watched.

All three functions have suddenly stopped working. The underlying code and admin panel are still in place—nothing has been removed—so I need someone to review the existing implementation, locate the breakpoints, and restore normal operation.

What I expect from you:
• Inspect the current installation and pinpoint why Siteingen, ad delivery, and the dual-credit system are failing.
• Apply quick, clean fixes so ads display again and the credit logic updates balances exactly as before.
• Test with a sample video and confirm that viewers see ads and both parties receive the correct payout.
• Provide a brief summary of changes so I can keep future maintenance simple.

Everything should be done on the live site; I can supply credentials as soon as we start. If you have solid experience troubleshooting ad integrations and reward logic on video platforms, this job should be straightforward.
