Hi Denzel,
OK, I did restore back to default settings and that brought back all the default pics and code I was working around. My footer was lost and, of course, anything that was associated with the sliders and content boxes, which were already gone anyway.
This was the best solution. I do not know what happened, but my question is: How do I prevent this from happening again?
Is it the Evolve backup for settings and customized code +
WordPress backup tool for content: pages and posts?
Thanks!
