Where do I get “Bug Information” to add to a question?

Question

I have exactly the same issue as this closed question and want to resolve it. In the comment section it asks the OP to add "Bug Information".

Where do I get bug information from so I can add it to my question on this stack?

I am new to WordPress (if thats not obvious) and I'm using WordPress 3.5.1 and the Weaver 2 theme
