I was working on wordpress and unfortunately I got some bad advice from a thread and need to get wordpress back up and running as quickly as possible. I had installed plug in to do backups and it called to change the chmod permissions in the main "wp-content" folder. I changed file permissions to 755 but also the recursive into sub directories was checked. Now nothing comes up when I go to the URL? Luckily I have a full back up of both the website and SQL databse, I have reinstalled the files but I still get a blank page? Where do I go from here?
