I have a store running magento 220.127.116.11 and I got hacked. Someone accessed the admin page - and added a paypal account, probably using an XSS vulnerability. I applied the patches SUPEE-1533, SUPEE-5344, SUPEE-5994, SUPEE-6285 and SUPEE-6482 with no problems (I think), but when I try to install SUPEE-6788 and SUPEE-7405 all the products disappear from the front page. (I have a backup)
I don't have SSH access and for that reason I followed this tutorial.
I was wondering, what patches to install for magento 18.104.22.168 in order to solve the vulnerabilities?
