Parallax pictures and site logo missing

Hi,

I am new to WP and I’m using enlightenment theme.

My site which is work-in-progress use to work well. However, since yesterday, I discovered that all my site parallax pictures (in the sliders) has gone missing. What’s left are just grey placeholders in their place.

Likewise, my site logo also went missing, living just the Alt-Text in its place.

Hope someone can help me. Thanks in advance.

Regards,

Bernard
