BTW, to answer your question, the error message above is what i got when trying to access my edit page (i.e. clicking my bookmark to https://brykmantra.com/wp-admin). I’ve been doing it that way for three years, so i never really give it much thought.
And now when i try the same thing, i just get a blank page, and it says “Done” in the status bar.
Oh, and another thing: I just renewed by domain name registration at Network Solutions, about the same time as this started happening. Is that a coincidence, or might that be a factor …
Sorry i didn’t bring this up earlier, but it didn’t occur to me …
Thanks again!
