Here is what TMD hosting sent me:
Please note that the issue is related to the status of the videos not automatically changing.
For example, when uploading a video, it transitions between multiple states:
For some reason, some of the videos are getting stuck in the Pending process, even though there should be no issues with their conversion.
Once a video gets stuck in the Pending state, all of the additionally uploaded videos would get stuck as well, until the issue has been resolved.
To resolve the issue, we enter the website's database and manually alter the state of the video.
Unfortunately, this issue is not server related and we would not be able to determine how to permanently resolve it.
You could consider contacting UNA's support regarding the matter and request more information on how to potentially resolve the issue.
Please do not hesitate to contact us again, if we can be of any further assistance.
