Right, so you want to dynamically alter what is displayed.

TBH, this is going down the PHP route, so I’d begin by looking at this.
You’ll want to strip/find some text in a string.

I’d break down your mini-program / function into steps. Get one part done and working before moving on to the next.~

Essentially, create a variable which will hold the image URL, and then call that when needed.

Okay, I forced a refresh – you’re right, they do disappear without the WWW.
But all the icons change.

Check the stylesheets and image folders – it literally looks to be two different sites at work here.

Okay, I’m sorry, I cannot read that, but it does look to be displaying correctly.

Can you screenshot what you see?

So rather than code it in, you want the server to do it for you?

Why can you not just type it in as you want it to be?

It sounds like a database error – just not connecting properly, or reading, or something went wrong there.

You may need to reset it somehow.
Check for plugins which updates the database (I honestly don’t know of any for posts/pages).
I used one for Media though.

If not, take a copy of the posts/pages, and then reset the database (there is a plugin), which removes all content (as though freshly installed).

Yea, if you cannot log in and change the URL in Settings you’ll have to do it in the database.

Essentially, log into the database where you installed WP and find the record with the URL. This needs to be changed to the working URL.

Once logged in, change it using WP-Admin. It may require a reinstall of WP if you installed it to the wrong directory.

<p class="myClass">some text</p>

.myClass { color:red; }

There you go – classes

.entry-content is a class – it looks like <div class="entry-content"> in the HTML
All P tags within that DIV have the indent.

Applying a similar method, you can add another class to the pages you want indenting (say blog posts) and style it in the CSS.

Though this means editing the actual PHP pages (maybe having variations), which is why I wanted to have a look.

Without knowing, I’d make two pages (index.php, page.php, for example).
Index has posts, Page has pages.

Index has <div class="entry-content posts">
Page has <div class="entry-content">

You then have your CSS as .posts p { text-indent:2rem; }

TBH, you can just do this with CSS classes.

If you link your site, I can have a look and make a suggestion.
