- Have canonical pages
- Don't trust code you haven't read/don't understand
- Make sure you view changes you make and that they are actually made when you think they are
- Make sure what you want to be rendered on the page is actually rendered
- Write tests
Seems like a bunch of tips for people who are just starting out with web development, to not miss the most obvious problems. How this post is currently on the top of the front page will forever be a question for me.

OP/Author here, to me too trust me
Fixed the RSS feed (and sitemap as well since both were not updated) Those scripts were silently skipped since January
Apologies for the inconvenience, it should be updated now!
