Questions & Answers about Tú tienes la culpa de este error, por eso debes corregirlo.
How exactly does por eso mean "that's why" in this sentence?
Why does the sentence use tienes la culpa instead of a form of the verb to be?
Why is lo attached to the end of corregir to make corregirlo?
Lo translates to "it" and refers back to este error. When you have a conjugated verb (debes) followed by an infinitive verb in its basic, unconjugated form (corregir), you can attach the object pronoun directly to the end of that infinitive.
