"Don't get/take something the wrong way" means not be offended, insulted, hurt, or angry by something someone is about to say. It's usually a good indication that you will be criticized for something that you did or that you should be doing something differently. Ex: Please don't take this the wrong way, but I think you should think about going to the dentist. Ex: Don't take this the wrong way, but have you thought about getting a gym membership?
