Sorry, I do not have a solution.

I would go to WordPress or whoever the theme belongs to and inquire. They have been great getting back to me with answers.I hope this has been resolved and this is too late.

Have not seen you around in a while

Thank you for your ideas...I have tried these and still no luck. Any other thoughts on why I am having this problem?

Make sure that the file name contains only letters and numbers and no punctuation. The apostrophe (') is the usual culprit.

It happens to me. I found that if I save the draft then refresh the screen it works.

Could be the naming of it. For example, if I title my photo like this:

my photo

It'll give me an error. But if I do this:

myphoto (no spaces)

It'll load fine, try this.
