I have not uncovered the source of this error message yet; as far as I can tell, everything in the settings is as it should be.
Last week the blog was inaccessible for a day or so. Once again, I could not determine why.
If I were the paranoid type, I would immediately assume that someone is running some low-level interference on the blog . . .
Who knows? Maybe someone is. People who use Blogger recently experienced some perplexing technical issues as well.
Whatever the case, I'm finding it difficult to write off the small cascade of glitches and errors I have had to deal with as mere coincidences. Let's hope the 'problems' are merely technical and accidental.
In the meantime, I encourage readers to take note of my email address on the sidebar in case this site mysteriously goes black one day.
