Can't see CSS changes on live site even after cache clear and force reload!

What’s your site URL?

Changing styles.css inside of the Arcadia theme should casue a change on the front end.

Are you using a child theme?

Nope, no child theme, just amending the original style.css
That’s what I can’t understand!

Can you add something to the bottom of that style.css file, let us know here and I can check to see if the changes are being made within the style.css file from within the browser.

You should be editing the file found in:
/wp-content/themes/arcadia/style.css

can you give exact examples of what you have edited in style.css, and what you were trying to change with the edits?

Well today I’ve tried to change

.logo-text span, .logo-img span {
font-size: 12px;
font-weight: normal;
letter-spacing: 4px;
line-height: 20px;
text-transform: uppercase;
}

to…

.logo-text span, .logo-img span {
font-size: 0px;
font-weight: normal;
letter-spacing: 4px;
line-height: 0px;
text-transform: uppercase;
}

Not a big change but still not being made.
The style.css file is changed to that in the theme editor and on the ftp but if you look at it through firebug or something the old css is still there.
It’s as if the cache isn’t cleared but I’ve done this a couple of times.

I would bet you’re editing the wrong file. The server shouldn’t be caching .css styles for that long.

Are using any caching plugins?

These are the styles I see in that file:

.logo-text span, .logo-img span {
    font-size: 0px;
    line-height: 0px;
    font-weight: normal;
    letter-spacing: 4px;
    text-transform: uppercase;
}

Nope, for sure not editing the wrong file.

I’m using Quick Cache.

If you analyse your css with the W3C CSS Validation service, you will see your css has multiple errors. Consider working through the list and removing as many errors as possible.
