My site which is six years old is now being hacked on a regular basis and someone is installing code on my site that deactivates the ssl certificate and makes it so the shopping cart doesn't work, thus no one can buy anything that I am selling. I remove the code and then someone goes in and hacks it again and again, over and over. Does anyone have any experience and how to get this to stop? Thanks in advance for any suggestions! The site is a wordpress site and is updated to the latest version.
