Hide Content
The main thing I can think of is if you deleted the page type it was using, or if maybe the page that it was looking for blog posts under was deleted and recreated elsewhere? There should always at least be an array to loop over even if it's empty.
A couple things to try:
* Does a normal page block work to display the same pages?
* Does a new Oembed Page List block work when just added? Or is it just this block / page, and something in the config options of the block? If config options, which ones?
* Does clearing the cache (including overrides cache) make any difference?
I'm also wondering if there's anything you changed on the site recently? It looks like your license is from August, I'm guessing it had been installed and used in the last five and a half months? It seems *really* odd that it would go from working to broken unless there were code or content changes somewhere...
