The Copyright line actually does support HTML. On my test community, I place in some HTML to render an icon logo with a container and it renders fine, along with a link.

The above is indeed accurate. Start at a smaller size and work your way up to a size that is suitable.

There should be a share icon at the top of each. Bear in mind this will only show if guests can view. Is this the case?

Robots exclusion (including robots.txt) is literally a standard: https://datatracker.ietf.org/doc/html/rfc9309
CSRF Keys are required on anything that changes the state of the application. The theme and language selectors are slightly different in how they work, they're forms that POST data when the buttons (themes) are selected. They still have CSRF key protection on them.
In the time that you've been repeatedly complaining, the bug report has been reviewed (as Marc said it would), addressed (for .19) and closed.

Along with this topic.

Solved by support via email.
The problem was a customised theme that was no longer receiving new code updates. This also meant the GTM/GA4 integrations weren't loading.
The solution was reverted those customisations, and implementing them via the appropriate manner. Thanks to this, the global template was up to par, and the integrations began working correctly.

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.
 

It depends on the betas 🙂 May well be before then.
You will be able to upgrade
Yes, version 5 will be available on our classic offering.
There arent any planned. Thats not to say prices will be the same forever, of course lol. But nothing planned at present
There are no plans for this at present. Feel free to post within our feedback area if you wish to see things like this added in the future. I would think however that dropbox and google drive probably wouldnt be suitable for the file storage side of a site

No problem. Glad to see thats sorted for you

Go to your Client Area (https://invisioncommunity.com/clientarea). Find your purchase and choose the link that says "Manage This Purchase". Below the Active User count is the info about your total space used.  

OK!!  I was able to get this working.  I edited the following file:
mod_security.conf and changed the configuration.  Then I restarted the web server.
SecRuleEngine Off After doing this I was able to update the file. 
Thank you for the help!

PS:  OFC, I re-enabled it again after the update was completed.

Glad to hear it. 🙂 Hope things are working better for you

Could you PM me the code you are seeing? I can then take a look. I suspect this is simply not where you think it is

Indeed adding or removing a reaction will update someones reputation count. 

You cannot remove that without modification. IF they have set  a password within the invision platform, they would need to enter it to get to the security and privacy section.

Please upload a fresh set of files from your client area, and then try visiting the upgrader again, in the first instance. If you then still have issues, please let us know

Pages is an application in which you can create pages or databases of pages in. Those pages could be named anything you like, and the databases and records could also be named anything you like. 
When you are looking at articles, that is just a pages database which has been called articles. Databases contain records that can be given a name. In this case, articles. 
So you have articles, which are stored in a database also named articles, which are within the pages application on our software. Of course you can create any number of things with the pages application, rather that articles. In an example here, we have created a database named recipes
 
 

You could bypass this by adding a constant.php file with the following in there. This will then at least allow you to get to the latest release, as it may be you have a bug in the release you are on ( it seems pretty old). Ensure you remove it once you are done
<?php define('BYPASS_UPGRADER_LOGIN', TRUE);  

If you havent restored already, we will have a new beta out very shortly which you can overwrite with and run the upgrader for

Word filters work with post content only at the present time

In terms of status updates, its worth pointing out these are deprecated items which will not exist in version 5. So if you are starting a new site, its probably advisable not to enable those at all.
In terms of feeds, you can create feeds of these things using the block manager. Please take a look at the following guide on this
 

If you change a price, when you save it will ask you if you want to amend it for people who are already subscribed
Same as above. However in this case, as they will not be on their first month, nothing really changes for them

There is no way in which to do this without modification to the platform

I have tagged our developers to see if they can advise on this for you
