I was helped by it although my first step is not one you have to take. I had a fantastic old fashion pity party. I cried and railed against the evil hackers (that where probably 13 and smarter then me) And then I did before I even started my site, what I should have done. And here is where I want you to start also. Learn hacked. The attractive thing about repair hacked wordpress site and why so many people recommend because it is official website so easy to learn, it is. Unfortunately, that can also be a detriment to the health of our sites. We need to learn how to put in a security fence.
Do not depend on your Web host - Many people rely on their web host to"do all that technical stuff for me", not realizing that sometimesthey see this don't! Far better to have the responsibility lie with you, instead of from your control.
Yes, you want to do regular backups of your website. I recommend at least a weekly database backup and a monthly "full" backup. More. Definitely more if you make changes and regular additions to your website. If you make changes multiple times every day, or have a community of people that are in there all the time, a daily backup should be a minimum.
Now we're getting into matters. Whenever you install WordPress, you need to edit the file config-sample.php and rename it to config.php. You need to install the database details there.
Of course you can install plugins to make your store like share buttons or automatic plugin. That's all. Your shop is now up and running!
