It all depends on how you set up your shipping methods. You can have “combined shipping”, but you need to pick one of those methods to calculate this. 

Yeah, the title and body field are “special fields”. You can’t edit them this way. Just like changing the order in the ACP doesn’t do anything. 

No. The images (thumbnail + hires) are created when you upload the image. You can’t call a different size. 
Database settings → Options tab 

Under Pages → Templates.
And yes, that’s the right way to add page-specific CSS. 

It should work. But is is now cached, so the results might be confusing because they are not in real time. 

It’s called “featured records” when you create it. 

What method/service is set up to send emails?
My guess would be that you use your hosting provider and they limit the amount of mails you can send out. 

In the ACP, got to Pages → Blocks → Create New Block
You will be able to create a custom instance of the feed block and you can add it on the front end as “Custom Block”. 

Yeah, your HTML is broken and it forces the text to be transparent in areas where it shouldn’t be transparent. 
I would try to turn off all 3rd-party plugins/apps and check the group formatting. Where does the coloring of the groups come from? Maybe that’s it. 

The meta tags can be overridden from any Pages template used to render the current page. You can add variables there as well. 
{{\IPS\Output::i()->metaTagsTitle = "Whatever ".$something ;}} {{\IPS\Output::i()->metaTags['og:description'] = "Something else" ;}} You can put that into the record template for example. 

{{if $formValue}} // Your code {{endif}} Wrap it all like this. 

Just click the “create new” button in the ACP. It’s as simple as that. 

The default custom CSS for the block looks something like this:
.app_cms_pagebuilderoembed_mp1qzgnrk { } Change it to:
.app_cms_pagebuilderoembed_mp1qzgnrk .ipsEmbeddedVideo { width:50%; } Just to give you an idea. Don’t copy this code. Targeting the .ipsEmbeddedVideo is the key. 

I repeat: “View word keys?”
That doesn’t require “highlighting”. 

Something to start with:
{{if $formValue}} <div class="ipsGrid ipsGrid_collapsePhone"> {{foreach $value as $file}} <div class="ipsGrid_span4 ipsSpacer_bottom"> <img src="{file='$file' extension='cms_Records'}" class="ipsImage"> </div> {{endforeach}} </div> {{endif}}  

Pretty sure that’s the spam protection kicking in. It has nothing to do with the Commerce settings. 

It works. 
Favicons are heavily cached by the browsers. Reloading a page doesn’t refresh them if they were changed. 

You can’t do that in the template code, because when it is parsed on the server, the server doesn’t know what device it will be displayed on. 
However, the IPS framework has CSS classed to achieve this, so while both statements would be in the HTML code for everyone, one part could show on mobile devices only and another one only on desktop.
 

It kind of exist already. You just need to create a custom Pages block from the widget you need permissions for. 

You need to use the template syntax as explained here on several pages.

Kind of. You can create a new page with Pages and then add the Activity Stream widget on it. It doesn’t allow you to chose an existing stream, but there are some settings to create a custom stream. 
You can also link a custom stream as “home” link from the menu, but that wouldn’t automatically picked up from other places like the logo. I am actually using that on one of my sites and I customized the logo template to link to “discover/6/”

IPS’ system already does that. Just upload the image here:
 

Yeah, it works like that. The featured records template is meant like a “blog homepage showing latest articles”. It doesn’t do much more. 
Everything to control this view is in the database settings:

You can narrow down the selection to certain categories or featured records only but that’s it. 

Click on the pencil icon first to activate custom permission. After that, the permission settings will appear in that drop-down menu.
