Very strange. For no apparent reason, my blog has just vanished:
Nothing comes out at all. But it is not a server problem - all pages on the site that are outside WordPress can be accessed. The database is all in order.
I put on PHP full error_reporting and nothing is reported. If I add some html/text to index.php, it is only displayed if the line requiring blogheader.php is commented out.
I had not been making any great changes to the site at the time. I had just signed it up to the TLB Ecosystem and to a Flickr related webring and I was adding some html to the sidebar. I removed the html that I had added, to see if that was affecting the blog's display.
Can anyone suggest anything?
