Hi,
Issue:
Your server doesn’t allow remote HTTP requests using wp_remote_get. You will have to visit this page manually to update which blocks are used on each page.
I am encountering the same problem. Commenting out line 69 does not help and I only have one template. I am using WordPress 3.4.2 and Multiple content blocks version 3.0.1.
Plugin is not great yet. Any help is very welcome….
