I removed the .html part from permalinks because someone suggested that would relieve CPU load. I have a BDP RSS feed showing up on the home page. Suddenly tho, the links generated by BDP RSS still had .html added at the end, and I got 404 errors when trying to click on the links to the articles. So then I added .html back to the permalinks and suddenly they dissappeared from BDP RSS links on the home page.
That's weird, right?
