are you sure you set all the options the same way as they were before?

I've added a lot of page list, removed a lot of them and never had such a problem. If we can't reproduce that problem it's highly unlikely that someone will be able to help you...

can you add it to other areas on your site?

what DOES show up in the block list?

did you turn advanced permissions on or no?

Nothing shows up. Not sure about the advance permissions- this is all new to me. My first time at trying to build a website.
