Videos from a category not loading

One of my categories is not getting any video updates for the last 2 full days. And I know those channels have been updated. Is there a limit to how many channels I can have? I have 21. other channels may not be loading either.

Should I delete the channel and then redo it?

btw, Is this forum still active?

Thanks
