Post the URL to your store? Unless it is a new development there is no self-protection feature. My first guess would be that whatever you or your hosting company uses as a firewall got triggered by the spike in bots using your contact form. Once this is resolved you need to change the contact form so that it has some kind of captcha. There are numerous tutorials online.

Your problem is that you are using GoDaddy. You'll regret that if your store gets any serious traffic. Also, the people handling their support don't know anything. If you insist on continuing with GoDaddy and their one-click install is broken which is what seems to be the case then you can try calling support and asking to elevate the call to a higher level of support who might be able to help you or you could ask for shell access and try to fix the issue yourself.

I don't see why you'd use a panel for an internal server -- this could be an issue caused by the panel.

My suggestion would be the same as razaro to use the Presto Changeo module if you could get it to work -- when I used shared hosting I was able to change php variables so I'd check if that is an option. Running an e-commerce site on shared hosting causes too many issues so I would suggest switching to VPS hosting. As for other options -- there are multiple options for programs that will sync the files on an FTP site. Just google sync FTP site and pick whatever you are most comfortable with. The database is a little more challenging but I've seen dockers for utilities that will connect to a remote database and create a backup on a schedule. Also, in my experience most shared hosting offers backups automatically. It has been a couple of years since I used shared hosting for anything but when I did I used to be able to just restore everything by contacting support.

The default FedEx module that comes with PrestaShop works on weight alone which gives you an approximate shipping cost when using multiple boxes -- I used it for a few months and shipping 150lbs in 2 75lb boxes vs shipping it as one 150lb box was basically the same cost (+/- $5). I didn't really care about the shipping being off by a few dollars but the problem with this is that FedEx has a max weight for a single box that I believe was 300lbs and we had orders exceeding that weight that would ship out in multiple boxes but this would result in no shipping quote from FedEx as the API would reject the box as being too heavy. My solution was to switch to Presto Chango's FedEx Module which handles multiple boxes. https://www.presto-changeo.com/prestashop-shipping-modules/137-prestashop-fedex-module.html The problem is that this will not fix your one product in multiple boxes problem since it is for figuring out how to get multiple products into the best combination of boxes. To address your issue without getting into custom work you'd need to use the Presto Chango module + figure out a way to treat the table as two products using something like a product pack. I've never used packs but it should get you where you want to go.

You need to give more details of why moving the store manually did not work.

I'm having a problem with saving sale notification e-mails from PrestaShop as text -- when I save any other e-mail I have in Outlook 2016 as text I get what I expect. When I try to save e-mails sent to me from PrestaShop informing me of an order as text I get mostly one character per line with some lines having a few characters but basically completely useless. Why would that be the case and how do I fix it?

You don't need a module -- just go to orders and there is a button that allows you to download an invoice in PDF format.

If you assign a value to the field when hiding them you can then just hide them without needing to worry about them being required.

Do you still have a working store on the original server? If yes move the store manually not using cPanel.

You can do what you want without a module. Where you would start to run into problems is that print products will have a very large number of combinations which could be an issue. You might also have options that are conditional in which case for that you would need a module. The big issue with print products is dealing with fix quantities which there is no module or way to do it without hacking at the code.

What do you mean by change controllers? I've been having 5-6 Russian e-mails per day for the last few weeks.

I've been running Prestashop 1.6 with php 7.x and no issues. I think I'm using 7.0 but can't remember.

I don't think so. I've seen a claim that it is possible but it seems excessively complicated and not worth doing. You can easily switch to MariaDB but not MondoDB. You could likely greatly improve performance with a server optimized for SQL

You don't do anything with PrestaShop. You place the file you get from Google in the top directory of your server.
