Livecam streaming showing up blank in our website (constant circle idling background)

Our live webcam website for an adult entertainment site was supposed to launch this past Friday. While doing last minute testing, we noticed the following within 2 of our 3 live stream modules. 1) The free access area for webcam models DOES display a feed. Customers DO see the webcam model from the other end; once they click on Private Chat and the request is accepted... 2) The the webcam model video feed background is white (blank). We can see the video stream circling/buffering, but nothing else happens. There is a small video feed of the customer on the bottom right that seems to be working just fine. 3) For group chat, there is a video carousel available. Same issue, except this room is able to include multiple video streams of customers who join a Group Chat. Users can see their own feed, but no one else's feed. The site is comprised of the following file types: php, js, css, and html. I currently have access to the remote server files via FileZilla and a zip file backup as well. At this point, we are willing to resolve the Private Chat issue only - since Group Chat is only something that only webcam performers control. Customers cannot request Group Chat. We originally purchased the script from [login to view URL] (supplier of adult entertainment scripts). Their staff, as we found out, are very poor and provided us this script with potential errors or perhaps forgetting to tie something and feed it properly to the "private-video-client" module. I'm way behind schedule at this time, and I was promised by the script staff that it would be resolved. It was not and I have lost all confidence in them. They have kept telling us..."a few more hours, just a few more" and they have completely saturated us financially with zero results. Can you help me please! In addition, we are looking for someone who can help us continue to improve and enhance our product as we begin to grow and generate profit, so we are still seeking for someone who is potentially interested in frequent enhancement work. My name is Felix; please email me or text me at 407-435-1217 I apologize for sending this out on a Sunday and interfering with your personal time, but I need your help. Thank you! Sincerely, Felix
