Frequently, in my work at an agency, I'll run into situations where the problem is occurring due to no specific cause. First things first, whenever I'm dealing with an unknown issue, I need to *identify the expected behavior*. Half the time, the behavior is obviously incorrect. The other half, it's not so clear. Sometimes, people say an issue is occurring when there is no literal issue, since the code doesn't match their expectations. Next, *identify the problem*. What is the problem, when does it happen? Where does it happen? What *causes the problem*? I can work backwards to determine that. Is the problem *input sensitive*? What's important is to keep a *running log* of observations that detail steps tried. At the very minimum, you can send this to another engineer to get help. Once the code is fixed, you're not done. What are the *side effects* of the fix ## Wordpress Specific * Any new updates or new plugins? Things you don't recognize? * Any settings changed? # References
