I have just begun using Drupal with Open Church theme. I deleted - daft, but curious - a block on the home page and now, of course, I keep getting Notice: Trying to get property of non-object in block_block_view() (line 245 of /home/cmdnew/public_html/modules/block/block.module). . I can find no way of rectifying this, nor can I restore the deleted blog. Help?!
