1. No rush.
2. I didn’t realize I could still set a start number, because the option is greyed out, but now I see you can do it if you first select how many posts you wish to scan. So I did what you suggested.
3. You are right, post #1448 is causing problems. Starting at 1449 allowed it to start again, but then it only did two. #1450 seems to be a problem post as well.
4. Looking at these two posts it is very easy to see what the problem is. The authors of these posts must have written their posts in MS Word and then pasted them into WordPress, creating lots of extra DIV tags, like this:
<blockquote><span style="font-size: 12pt; line-height: 115%; font-family: "Times New Roman","serif";"> ... </span>
... <em>...</em><span>...</span>.
<div style="text-align: left;"><span style="font-size: 12pt; line-height: 115%; font-family: "Times New Roman","serif"; color: black;">...</span> <span style="font-size: 12pt; line-height: 115%; font-family: "Times New Roman","serif"; color: black;"> </span> <span style="font-size: 12pt; line-height: 115%; font-family: "Times New Roman","serif"; color: black;"> ...<span> </span>...</span></div></blockquote>
It seems that QQWorld is choking on this ugly code…
