Images and texts not showing

I’ve seen a couple posts related to this problem but none of them provide a clear solution. The only thing I’ve seen is clear cache which I’ve done quite a few times.

The issue: I’m only able to see the border, previous and next buttons, and the circles below the slider. If I include a title to the slider it also shows up. None of the texts or images appear even though the markup is there when I inspect it in Chrome. What could cause this issue and how can I resolve it?
