Hi, On iPhone emulator articles seems to be OK.

1. Do you have this problem on all pages and articles OR only on selected? If selected please share URL to them, I will check deeper.
2. Use "Hidden Content" here on forum to share access to admin area as Super User.

Please inside custom.css file add this:

@media (max-width: 580px) { 
.view-article article.item {
    padding: 0 20px !important;
    float: none !important;}
    article.item .content-wrap { margin-top: 25px;}
}

Then clear mobile browser cache deeply AND refresh 3x browser to see changes, it should help.

Added the css - cleared the mobile cache - seems to have worked.

I'll be checking further.

Why has nobody else seen this? Why wouldn't it be in the normal CSS for this problem?

THANK YOU PROFESSOR FRANKOWSKI!!!

To be honest, it should be fixed a long time ago. You're welcome.

One day I wanted to be a doctor of law after study, but now as you see I cure websites. :)
