Yes, I am able to successfully edit non active themes.

But If I edit active theme file WordPress deletes all of it’s code & make it zero kb file.

Thanks Jeremy, I think problem is theme specific.

Thanks again for answer.

I mark topic as resolved.

Hi Jeremy,

It seems it is Apple Safari specific problem, This error occurs only on Safari browser but it is working fine on Chrome & Firefox.

Here is screenshots how it is looking at my side,

Hi Eric,

I solved it with relevant CSS technique. Thanks for suggestion.

Here is the solution I posted on my website for the same: https://mandarapte.com/tutorials/creating-datafeedr-ads-wordpress-plugin-multi-columns-ads-layout-css-how/

I am using CSS Version 2.1 with XHTML running WordPress 3.8.1

Hi Eric,

Can you explain with example please… As I am not CSS Geek or expert…

Which syntax I should use & how?

Thanks & Regards
