I had quotation marks in my title field:

Should I Call It a "Mental Model?"

I have an intro paragraph and a follow-on page, so the "Read more about" link also had quotation marks. It previewed just fine. When I published it, the error appeared when I clicked the "Read more about" link, and also when I clicked the title link. I removed the quotation marks from the title field, and now it works fine. However, the "Read more about" link preserved the quotation marks I had removed. No biggie, just odd. The error, though, that's a biggie. I can reproduce it.

Parse error: parse error, unexpected T_STRING on line 17

The "Read more" bit of text is being processed to translate it into the appropriate language. Because you have text in quotes within that, it's probably trying to figure out how to parse that. You could try using " instead of ".
