I didn't build this website but we discovered these lines of broken code polluting our clients website. We said we could fix it but when I went into it, thinking the problem was the Contact Form plug in, I couldn't access the wp-admin at all. I went into the ftp and deleted the contact form 7 plugin and completely broke the site, did a restore of the plugin and it remained broken.
I have limited knowledge of troubleshooting php so I don't have clue what is happening here. Does anyone have any suggestions of things I should try to just get my clients original website back up?
