Index.php page gone?

It’s working now, but the index.php isn’t showing how it’s meant to, it’s meant to have a divider inbetween the post’s like on the about page, but it’s written on https://elmiee.tingilye.net/wp-content/themes/Elmiee%20Blog/index.php
but that’s coming up with a error and I don’t know how ti fix it?

anyone help? I don’t know what to do or where to look

also when you go from index.php to about.php the layout shifts around and doesn’t stay in the centre, how would I fix this? This is how wordpress seemed to have gone wrong, me trying to make my layout stop jumping =/

You should never try to use URIs like this:
https://elmiee.tingilye.net/wp-content/themes/Elmiee%20Blog/index.php

If you want to post the code, use phps or txt files.
Or use https://pastebin.com

Maybe the code for displaying the divider is not correct (I can’t see it in the source code).

[code moderated - read the previous post]

That's the index page that's in the template folder, as you can see the divider /is/ there but it's just not showing up, and the code is right for it because it was working before

No long code here, read my previous post, please!
