Make sure you have PHP's mbstring extension loaded.

Check your PMs - just threw something together over lunch.

Use the following HTML in your content source:
Audio:
<audio controls> <source src="URL"> </audio> OR <audio src="URL" controls></audio> Video:
<video controls> <source src="URL"> </video> OR <video src="URL" controls></video>

Template: forums -> front -> topics -> topic
Locate:
<ul class='ipsTopicMeta'> {{if isset( $comment->metaData['comment']['moderation'] )}} {{foreach $comment->metaData['comment']['moderation'] as $modAction}} <li class="ipsTopicMeta__item ipsTopicMeta__item--moderation"> <span class='ipsTopicMeta__time ipsType_light'>{datetime="$modAction['row']['ctime']" short="true"}</span> <span class='ipsTopicMeta__action'>{$modAction['blurb']}</span> </li> {{endforeach}} {{endif}} {{if isset( $comment->metaData['comment']['timeGap'] )}} <li class="ipsTopicMeta__item ipsTopicMeta__item--time"> {$comment->metaData['comment']['timeGap']['blurb']}... </li> {{endif}} </ul> Remove the following from within that:
{{if isset( $comment->metaData['comment']['moderation'] )}} {{foreach $comment->metaData['comment']['moderation'] as $modAction}} <li class="ipsTopicMeta__item ipsTopicMeta__item--moderation"> <span class='ipsTopicMeta__time ipsType_light'>{datetime="$modAction['row']['ctime']" short="true"}</span> <span class='ipsTopicMeta__action'>{$modAction['blurb']}</span> </li> {{endforeach}} {{endif}} Keep in mind that will also remove any other moderation action logs that this section might contain - not seen anything else myself, but there may be something else.

By putting the colour in to the html code...
<span style="color:green"><strong>Group name</strong></span>  

Go to your ACP, type 'topic summary' and enjoy...

The template you would need to edit it is forums -> front -> topics ->topic.
Search for the following in there:
{{if $topic->canEdit()}} <span class='ipsType_break ipsContained' data-controller="core.front.core.moderation"> <span data-role="editableTitle" title='{lang="click_hold_edit"}'>{$topic->title}</span> </span> {{else}} <span class='ipsType_break ipsContained'> <span>{$topic->title}</span> </span> {{endif}} Within that, you can add in the following items to display information about the forum:
{$topic->container()->metaTitle()} {$topic->container()->metaDescription()} Example - replacing the above with the below gives you the result in the image:
{{if $topic->canEdit()}} <span class='ipsType_break ipsContained' data-controller="core.front.core.moderation"> <span data-role="editableTitle" title='{lang="click_hold_edit"}'>{$topic->title}</span> <br> <span>{$topic->container()->metaTitle()}</span> <span>{$topic->container()->metaDescription()}</span> </span> {{else}} <span class='ipsType_break ipsContained'> <span>{$topic->title}</span> <br> <span>{$topic->container()->metaTitle()}</span> <span>{$topic->container()->metaDescription()}</span> </span> {{endif}}

Yup, it's not ideal but it's the best that could potentially be done from a CSS point of view.
@Apfelstrudel a way to see how the CSS can 'go wrong' would be to disable your Messenger....this will then remove it from the notifications list, and Newsletters will have a different numbered row and then something else will be hidden.
Here's a plugin which will do it the @Daniel F way 😉
 
(NE) Remove 'Newsletters' from notification settings.xml

Search for 'topic summary' in your ACP

Group setting, "Can report content?"

They are having issues with their license server at the moment.

I'm off out...try to navigate yourself to the following URL:
admin/?app=core&module=overview&controller=files&do=configurationForm&id=1
And then modify the field that contains the 'Directory'
If you cannot do the above, then either:
1) Search in phpmyadmin for the path you currently have or
2) Log a ticket with support.

Search your ACP for 'Reputation' and you will find the relevant settings - enabling it, setting what each user group can do etc.

One question...have you purchased the 'Commerce' application (used to be called 'nexus') when you did the following:
"So I was forced to purchase the software all over again "
because what you are being told there is that you have it on your site but the files are not for the version you are trying to upgrade to.....in other words they are not included in the package of files you have uploaded.

It will only affect your account to allow you do the action it provides.
The action leads to a result, which all will see.
Just try it.

Type 'profile' in to the ACP search...

Click the 'Additional information' tab (although in the case of that one there isn't a support topic listed)
Anyway...that is where the support link (if provided) is now displayed.
