It appears I'm able to edit things slightly better today which is great but doesn't explain why it's still so buggy.
As you can see from this screen recording: https://www.awesomescreenshot.com/video/8655064?key=642486191c18805c4573eeea30aea71c
I've made changes on both the contact page, abnd the links page within the editor, but they are not appearing the same on the front end of the site.
You'll see on the contact page, the text box under the title 'Tuggerah' is exactly the same and the one below under the title 'Newcastle' in the editor, but on the front end on all devices it's not showing the same.
Also on the links page, I've given padding to the text for each box and it is showing correctly in the editor, but not on the front end of the site.
This is happening for other pages too.
I've cleared joomla cache, browser cache etc. Tried other browsers and it's the same.
Please advise.
