When performing a restore, you would need to restore the entire site, including all files, and not just the database. (From your wording I can't be certain what you restored.)
This is because you'll have the files for the new version present, but trying to use an old database's information.

So, what are you guys managing to do with the time you've saved reading these items faster?

Typographer’s nightmare. 

In a word, "Yes".
You can configure Commerce to either change a Primary Group, or add a Secondary Group, for a member.
The Group you assign will determine what they can see, based on what Group permissions you have setup, and you can set Ads to show only to selected Groups.
Please check our documentation for Commerce, starting here:
 

Why you gotta do me like this?

We'll doubly make sure we look at it then 👍🏻

That would be @Mark H cooking 🤐 . 

Haha. Me unveiling the Alerts System:

Shhh... Jordan doesn't know he's volunteered yet. 😇

Bingo! That was it. Web server was using 8.0.19 and the CLI was using 8.1. I updated the CLI to use 8.0 and the maintenance script ran without error. 
Thank you both @Stuart Silvester and @Jim M

Your screenshot is for the inbound TLS connection to your server.  Meaning someone accessing YOUR website.  In this case, you're making an OUTBOUND connection to IPS.   When your server makes a connection to a remote server...  it tells the remote server what versions of TLS that it can use.  From your first screenshot, your server looks to be only offering TLS 1.0.  IPS servers are saying "Sorry, we don't accept 1.0".  
In most cases, it would offer 1.1,1,2, and 1.3.  The destination would review the available choices and pick one (typically the most secure version) and say "let's use this".  So in this case, your server needs to offer up better choices basically.  🙂 

That is not a logo.  It's a favicon.

Check the settings of the Group(s) they are in, Social sub-tab, Messages sub-section, and see how many conversations they are allowed to start.

We are simply following our internal security policy in asking for proof that you are who you claim to be, nothing more than that. We aren't trying to strong-arm you into renewing. 🙂
Asking us to cancel an account. when the request comes from an email which is not associated to the purchase at all, is something we cannot do without proof. This protects both the integrity of your account, and us, from malicious actors.
Since you said the email used to register can't be used, we asked for an alternative way to prove your identity, in the form of a government-issued identification. (You did previously reply, "If you allow any other verification, please do let me know." We did offer the alternative method, which you indicated you were not comfortable doing.)
This has been policy for a very long time when an email address expires or is deleted, and we receive a request to cancel an account, license, or package. I'm sorry you feel this is not an acceptable way to do this.
That said, if you've removed your credit card from the Client Area, any renewal would go unpaid and eventually expire on its own.

thank you very much, now it's working

We have the following guide on how to perform upgrades: https://invisioncommunity.com/4guides/welcome/install-and-upgrade-r259/
 
However, there isn't really a best practice list outside of what I mentioned in my other post. I would recommend the below, seeing as you are so far behind in updates. Additionally, setting up a test install may be a good idea if you have a lot of customizations to test or simply want to test upgrading.
Before performing any core software upgrades, do some research of the third party applications/plugins/themes/etc... you have installed and see what is available for the most recent release. If you there are any that aren't mission critical, now is a good time to perhaps uninstall those. When you're ready to perform the core update: Turn your community offline. Take a full backup (database and files).  (for those reading who are cloud, you're all set here) Disable all third party applications, plugins, and language packs. Create an unmodified theme and set it as the default theme (ensure your administrators who are helping with the upgrade use that theme) Perform the core upgrade. As you are so far behind, it may be a good idea to perform a manual upgrade (see guide above for more details on that). If any issues with the core upgrade, please create a topic here and someone will help you 🙂 . Have a look over your community to ensure things went well. This is a good idea for the next step. Once the core upgrade completes, you will want to consider looking at getting your third party items in line: As you are coming from 4.4, you will want to setup the Marketplace integration and go through onboarding. There should be a notification to do this in the notification bell of the ACP (top right). This will step you through which applications/plugins/themes/language packs you have installed from the Marketplace or are custom (aka custom development you had done or installed from elsewhere). You will want to upgrade each application/plugin/theme/language pack independently and then test before moving to the next one. This will allow you to tell what may be breaking and causing that break. For third party items which have no compatible release with our core software you just upgraded to, be very cautious of enabling these but ultimately, enabling these independently of others is advised. Done! These "best practices" are really an extremely cautious approach coming from a rather old version. Point upgrades (e.g. 4.6.11 to 4.6.12), you likely would not need to be this cautious but I would stress item 2.2 (Backups) for any self-hosted client for any upgrade, no matter how small.

thank you so much for your detailed answer!!!! much appreciated. 
I know, smaller in between updates have always been superfast and a piece of cake   🤩

Checking my notes from way back when...
MariaDB 10.1 was the sweet spot between 3.4.9 & 4.5.x - meaning both versions could run on the SQL server.

thank you very much, i have to see what my server has to offer 😉

Thank you.
I've flagged this topic for dev review, to see if there is a way to accomplish what you want without complex CSS (which, in another topic, was suggested as the only way to do this right now).
