I typed it directly into the text box.
I copied it and repasted it in plain text.
I pasted it into Word, copied that and pasted in plain text
Then as a last resort, I typed it again a second time directly in the text box.

After that, I eliminated one sentence at a time from the end of the text and checked spellcheck until it stopped giving me the 403 error

Tested just the last sentence eliminated and got the 403 error again.

Then I deleted word by word from the front and back of the sentence until no error, then added back in a character at a time until it reappeared.

Whatever bugs it is in this phrase:

I'd love to know if you get the same error when you type in that phrase. (I just retyped it and got the same error.)

I'm usually the one doing IT problem solving. This one has me stymied.
