Storing passwords in plain text.

To be fair, it was a feature requested by the client, but still...

At least encrypt it man.

Our client got mad once because the website we were building didn’t function on the Instagram in-app browser.
I guess it was kinda my fault because it was due to a cached JavaScript file which threw an error on a newer version of the page (that’s when I learned about cache busting) but still, I kinda felt that’s a little ridiculous to get mad about.
