Once you have move your software to the /forum/ directory, the images broke and do not display properly? Using the support tool to clear the cache will fix this problem. Also, is this a problem on the default theme as well (assuming you have it still)? If so, have you tried to clear your web browser's cache? You can also try to flush your dns via command prompt:
ipconfig /flushdns  

Inside the AdminCP under Customizations, edit the English language and use the search bar for "Forums".

I use Webflake's Nulled software (4.4.10) and I haven't had any problems. Also, you have to change the blank config file name to remove the ".dist" part in order to install.

First, I would like to say thank you for posting code you want edited. Most users ask for us to edit code we do not know/have access to. Here is your edited code:

Add a group suffix to the existing group you'd like to edit.
<i class="fa fa-check-circle-o" aria-hidden="true"></i>  

Inspect Element > find the css for the specific icon > Override with custom.css code to change icon

forums -> topics -> postContainer:
Change:
<aside class='ipsComment_author cAuthorPane ipsColumn ipsColumn_medium'> With:
<aside class='ipsComment_author cAuthorPane ipsColumn ipsColumn_medium' style='{{if $comment->author()->member_group_id == 4}}background: linear-gradient(to bottom, rgba(15,183,255,0.2) 0%,rgba(15,183,255,0) 100%);{{endif}}'> Change background and member group id to whatever needed.

You can do this with the way I added a gradient text color to the time on WebFlake that appears in your author pane.
background-image: -webkit-gradient( linear,left top,right top,color-stop(0,#ffd728),color-stop(1,#ff7328) ); color: transparent; -webkit-background-clip: text;  

body { background: url(...); }  

Just use the converter provided in the software and it's pretty easy. 

Post in custom.css
.cForumList .ipsDataItem_unread .ipsDataItem_title:before, .cForumGrid_unread .ipsPhotoPanel h3 a:before { content: "NAUJA"; }  

Something you should probably look into - https://support.cloudflare.com/hc/en-us/articles/201897700#h_533849564801543957037974

You can use CSS to do this:
.cke_wysiwyg_div > p { color: #fff; }  

PHP 5.6 isn’t compatible with IPS 4.4. You’d need to have 7.0, 7.2, or 7.3. 7.1 is known to not work.

While in the Live Meta Tag Editor, search for the og:title in the right sidebar.

You could just combine the Who Was Online plugin with the Who is Online plugin. ?

.cAnnouncementIcon, #cAnnouncementSidebar h3 { display: none; }  

Images should be 20 x 20 and should include a padding-bottom of 2 pixels.

Run the support tool in admin cp
