Jobee, I'm sorry but it is difficult to understand you issue. First you say about photos, then videos. Can you please provide screenshots or video what is the issue with the loading on your website?
Sorry, I meant photos, not videos. It's all about the photos page.
When you scroll down the photos page, when you get to the end of the initially loaded photos, it automatically loads another bunch of photos. (or it USED TO load another bunch of photos before the server move).
I have a theme with a global sidebar, and I have several items in the global sidebar that pushes the bottom of the page farther down than the first initial load of photos. So there is a big blank area between the initial load of photos, and the bottom of the page, because the sidebar lengthens the page.
It used to be that when you scrolled down to where the first bunch of photos ended, it would load another bunch. But since the server move, it doesn't load more photos unless you scroll all the way to the bottom of the page, then upon beginning to scroll back up, more photos begin loading.
I'm don't think it's that big of a deal, but it's perplexing why that function changed.
