I have a client that I am setting up a site for and we had set up some placeholder links on the page defaults that are set up in a content block and added as a global block in the scrapbook. I went to delete that global block to set up the actual links in a new global block and add that to the page defaults, but the old block still shows up on every page. Is there any way to delete these blocks across multiple pages? would there be a simpler way to handle this through the database? They have upwards of 100+ pages set up already, and it would mean having to update each page individually by manually deleting the block on each page.
