I had to restore my website 4 times because out of the blue i lost all of my data ,.
I dont know i just had to reset my website again because my HTML code etc. just disappeared. Is there anyway i can restore it to the one version I had updated few hours ago. Thanks
You should start using some form of version control software such as git or SVN.
If you don't have a back of the code, or don't use version control it is impossible for you to roll back the code. You should look into using git if you want to be able to go forward/backwards in time.
Another option is to roll back your entire server to a backup image if you have one, but then you lose all your applications/files that were add in between the creation of the image and now.
