Hi @mahesh,
Thank you for your answer.
In fact (and excuse my bad english :-)) in 2015, I worked directly on the CSS code to modify my theme (i work on wordpress site and not directly on the FTP servor). I didn’t upgrade CatchBox for a while and I never created a child theme (I know, not good at all :-S).
When I upgraded in december, of course, all my modifications vanished.
Hopefully my web hosting had a safeguard (good word?).
As my website is a way to join my onlineshop I had to put it back, even if it was not perfect.
So, I copy/paste my entire css code of my past version of Catchbox, but now, not directly in the editor of the code but in the page named in french “modifier le CSS” : modify the CSS.
I think it’s why it’s bugging.
When I saw it was not good, I cleaned this code in and I just kept the part of the code really modifying the theme. I checked I didn’t copy/paste a part of code which was about the responsive theme.
But it’s not working 🙁
I use plugin on my theme, but not to write my custom CSS (if it’s your question). I use Jetpack and I customize it on my custom CSS.
Maybe it’s the problem? Because the code I use, I write it with the Jetpack helper.
With this explanations, does it help you to understand better my issue?
Thanks 🙂
