Minimum is PHP 7.4 so need to have your hosting provider upgrade you to a server with it or change providers. There is no other option if you can’t run minimally PHP 7.4, I’m afraid. 

Support is still covered under self-hosted licenses. The avenue to receive support has only changed. Our same staff will be here to assist you in this forum for any software support needs. Our staff has access to the client area to obtain secure access to your access details you provide and we can escalate your ticket, should it require doing so.
What is it that you require support for? We’re here to help 🙂. 

This is the browser coming back to you with this information because you are not running the site (I presume) with an SSL certificate and over HTTPS. The web has switched to being a security concise place so browsers will now warn you if you are on an HTTP website and submitting forms with sensitive information, such as login credentials.
You would need to get with your hosting provider/server administrator and add an SSL certificate to the server. Then follow the instructions below to ensure your community is running over HTTPS:
 

Please ensure your database tables are set to dynamic, not compact. Otherwise, you will run into this issue. Please contact your hosting provider for assistance.

You can check your email inbox for any communication from tickets 🙂 . There are no other means to view it.

Just to update, this should be resolved now.

Our team has identified the issue so things should be working now.

Please ensure in the Client Area you opt to include the conversion application.

Looking in your ACP, it looks like you're using a custom language pack. Are you using that language pack during the conversion? If so, I would switch to an unmodified English language pack as something seems off here.

Sorry, there are no current means at this time. The download database setting here is for being able to move templates and related items between instances, not backing up the Pages Database.
In our Cloud, we do have in-depth backups so there would be few cases where you would require your backup outside of personal needs or moving off the platform. However, on request, we can provide you with your data.

Unfortunately, the message in the ACP is simply relaying what PHP has in it so this is not something which we can assist you much with. Your hosting provider would need to investigate PHP and see why these functions are not disabled on your server.
Additionally, keep in mind this is simply a recommendation from our end to better your security. It is entirely up to you and hosting provider/server administrator to agree/implement. If you're on shared hosting, many providers will not disable these due to that. If this is something which you want to be a part of your security plan, you may need to change providers to do so if they are unwilling to help.

The only recommendation here would be to restore your database to before the deletion then delete them via the software. Manually deleting data from the database is not recommended or supported.

Looking at the page in question, this is due to you are already using that block on that page so you would not be able to utilize it again.

Inviting members would be expected in types which have membership options. There is no straight up add button unless you mean adding something else? It could be you were using a third party solution here prior which is no longer working.

It looks like you had numerous Javascript errors. After clearing system caches in ACP -> Support -> Clear System Caches, this has been resolved so they should be able to post. If you're still having issues, please clear your browser's cache as well.
If anyone is still having issues logging in, we would need to know the exact user.
 
 

Sorry, we do not recommend making manual queries, nor do we support it. If you make a manual query, it is your responsibility to ensure you have retained backups and if it goes wrong, you will need to restore those backups.

An update to this - a colleague reached out to me and said that upgrading to 4.7 should fix your corruption issue with theme resources as it should replace them. Please try that now and let us know how it goes!

I have removed the demo features so you should be good now. Please do not remove these items with CSS when asking for support as it will complicate and prolong the issue you're encountering.
Additionally, please see the email we sent you regarding the copyright/branding notice which is required.

This would not be in the software but a hosting support question. 

You ran the requirements checker on your PHP 7.4 which, as you stated, is working. You would need to run it on the PHP version you're attempting to upgrade to which is not working.
To fix the collation issue, you would need to run the converter as mentioned. 

As mentioned by Randy, you will want to ensure that the URL you are installing at is 100% what is on file down to HTTP/HTTPS and www/non-www. 
When going to the URL we have on file, I am seeing an installed software so looks like you got this working but if you did not, please clarify.

As mentioned by others in this topic, this looks to be the alert system (issued by your moderator) and a theme bug. You'll want to work with your theme's author to resolve the issue.

Glad to hear you found a possible solution on forums here. They are great resource to find out what other administrators are facing 🙂 .
For other user's reading this topic, this is an example topic:
 

Your license is indeed restricted to the URL, not the domain or sub-domain.
When switching from HTTP to HTTPS or www to non-www, you would just need to re-add your license key to the ACP -> System -> License Key. It does not require a full license URL reset.
However, in this instance, I have updated your license URL for you.

Please refresh your license key by going to ACP -> System -> License Key. There were some changes in our recent release and cause some inconsistencies. Apologizes for the inconvenience.
