Microsoft no longer allow a 'Never' expiry - 2 years is the limit (so that's an update for the document)
Value (it states that in step 7 of the guide) - has to be grabbed at the time of creation, as it is obscured from view on later views. If you didn't grab it then just delete the existing one and create a new one.
And the final tip...put a reminder into your calendar for a few days prior to the expiry date, to remind you to create a new value.

Samsung?
 

Take a look at \IPS\Login::usernameIsInUse (system\login\login.php)

app = core
location = global
group = global
{template="memberBaddge" app="core" location="global" group="global" params="$comment->author()"} If you had it in core -> front -> global then your code would be fine as postContainer is in front too.
 

0 = false
1 = true

Step 1 - create a group
Step 2 - give that group moderator permissions
Have you now done both?

I don't think you've noticed that the provided atachment link is missing the &key parameter which, if missing, means that the attachment won't be accessible even if it was there because a security check fails as a result - and will present the following message:

 
If it was me investigating this, I would be looking at the content that contains the attachment link, to determine if it is missing the key element there. If so then it was possibly posted in a version when the &key= element wasn't being added to attachment links due to an IPS bug that has since been resolved...but hey, that's me.
 
 

Right click the item and inspect the item before you click it and then after you click it, then find the classes that are applied to it before/after:
BEFORE

AFTER

From the dev tools css files - the color isn't changing, the opacity is:
.cToken.cToken_selected { opacity: 0.7; } So override it...
.cToken.cToken_selected { opacity: 1 !important; } This kind of stuff is usually a lot easier for others to figure out if you post a link to a site (which allows people to look at the html/css) instead of a screenshot (which only allows people to look at a pretty picture)

Use CSS
.ipsEmoji{ font-size:96px; }

Template edit:
core -> front -> messaging -> template
Find:
<li class='ipsMenu_item {{if ! empty(request.search['recipient'])}}ipsMenu_itemChecked{{endif}}' data-ipsMenuValue='recipient'><a href='#'><input type="checkbox" name="search[recipient]" {{if ! empty(request.search['recipient'])}}checked="checked"{{endif}} recipientvalue="1" id="search_recipient"> {lang="messenger_recipient_name"}</a></li> <li class='ipsMenu_item {{if ! empty(request.search['sender'])}}ipsMenu_itemChecked{{endif}}' data-ipsMenuValue='sender'><a href='#'><input type="checkbox" name="search[sender]" {{if ! empty(request.search['sender'])}}checked="checked"{{endif}} value="1" id="search_sender"> {lang="messenger_sender_name"}</a></li> Remove the if/endif either side of ipsMenu_itemChecked and checked="checked"

edit your globalTemplate template and add the following prior to the closing </body> and save your template.
<script> if(typeof CKEDITOR !='undefined'){ CKEDITOR.addCss(".cke_editable{cursor:text; font-size: 20px; font-family: Georgia;}"); CKEDITOR.config.font_defaultLabel='Georgia'; CKEDITOR.config.fontSize_defaultLabel='20px'; } </script> What does it do...
If there is a CKEDITOR on the page then... It changes the CSS of the editor to be the font/font-size you want and then... It changes the label of the font dropdown box and... It changes the label of the font size dropdown box.  

{{if request.app =='forums'}} {{endif}}  

That's actually an indication that your PHP version doesn't have the mbstring extension available to it.
Download this https://invisioncommunity.com/files/file/7046-invision-community-requirements-checker/ and upload it to your site's root. Switch to PHP 8.0.x, open the file in the browser, fix any of the red items, then go from there.

If the 2 licenses include the exact same suite elements, go for it.
But if they differ (example: 1 has Pages, the other doesn't) then download the correct package for the license.

This happens if you drag/drop a file into the editor's text box, as opposed to the location that clearly states "Drag files here to attach..."
Same situation as this...

You'll probably have to do some formatting of the date in Excel to get correct values - I'm just exporting what is displayed in the ACP.
If you can't get that sorted, then here's a change that will export the date as a UNIX timestamp instead.
(NE) Download attachments report 1.0.1.xml
You can then use this formula to recalcultate the UNIX timestamp to a numerical value that Excel can use for a date/time:
=(C2/86400)+DATE(1970,1,1)  

If 'Rules' = 'Automation Rules' then that's a dead application...long time ago.

Use the search functionality in the Members listing:

And when you get the results then you will see a "Prune Members Found" link that will allow you to mass delete.

Easily reproducible:
Create an alert that requires the user to respond View the alert as a targeted user Send the required PM View the PM as the intended recipient - all good Delete the alert View the PM as the intended recipient - yep, it's f.... I've got 3 PMs on my test site that have this issue - and I know they are all associated with my alert testing, and all my alerts are since deleted.
Stick a var_dump($conversation->alert); in before this, and you'll get NULL for a normal PM, and an integer for a PM that came as a result of an alert:
if ($conversation->alert) { try { $alert = \IPS\core\Alerts\Alert::load($conversation->alert); } catch (\OutOfRangeException $e) { } if (!$alert->forMember(\IPS\Member::loggedIn())) { $alert = NULL; } }  

It's not a ckeditor plugin - it's an IPS plugin, so go into that section of the ACP and manually install it (assuming you are on a plan that allows custom apps and plugins)

In Pages, do the following:
Create a folder called 'central-de-ajuda' (click 'Add folder') In that folder, create a page and set the filename to 'centraldeajuda.html'
 

Pretty sure that if you perform an advanced search in the Members list, and then click on the 'Prune members found' link on the top of the results - the members are removed, but the content is kept behind as 'Guest'
Test it out with a single user (perform a search that will find that single user) to confirm, then try it with a search that will return 2 users to further confirm.
