Waking up with a nightmare

Hi all.
There is nothing worse than waking up early in the morning to find your site is hacked.
There is nothing more annoying to wake up with an error.
So thursday morning I get up early to do a few things only to check email and get an odd message I have never gotten before.
From google search console.
Crawl error with one page, index failure.Solution, not sure.
Site works, page works, so assume a network brounout for 1 or 2 seconds, during index, logical solution is request entire domain index.
Mean time I decided to go and do a health scan.
1. run health scan.
Warnings!
1. you do not have the latest php.
2. your site is not secure.
3. you are missing some optional modules.
Searching all things, 3, doesn’t matter, however I did a download of another php tool for plugins so hopefully things don’t go stupid.
Next ssl, do we have ssl?
Easiest solution for me is to update and get ssl on the site.
Since I don’t have that sort of access the easiest way was to set up cloudflare which I did but not sure if I will bother using as I found out we have ssl already.
So install simple ssl, enable it and set it all up.
So thats up.
So if you get the site in https by default thats why.
Technically it doesn’t matter if we have ssl or not but google puts search ranks up for it so its a good idea.
So thats all that.
