WOW, this makes no sense, but when I get rid of the sentence
This style is made with premium quality, select American Range Bison from ranches in South Dakota.
it works fine. I can make the description as long as I want from there, so long as I don’t have that phrase.
And it’s not special characters, because I even retyped the whole thing from scratch in Notepad.
Therefore, it’s NOT character limit.
But the question remains: WTH??????
UPDATE: It’s the word “select” ... if I get rid of just that word, it works. I can add it to a different sentence, and sometimes it works. Haven’t figured out the exact pattern, but could it be that “select” is in the command syntax of either mySQL or how the cart processes it?
