Style sheets rendering differently

Check if the source codes are the same https://diffchecker.com

What do you mean by source codes? where are those?

I’ve double checked the style sheets with that link you posted and the only differences it throws are the ones relating to the button in the nav bar which is expected.

Right click where applicable on the page and select ‘View source’. The source code is the code in the new window that pops up.

I get you, the page source.
It tells me both files are identical.

Could you make sure your french link is correct?

Odd!

Here it is: https://fr.social-be.be/

Try deactivating all plugins on the website that has no blue bar at the top.

Deactivated plugins on both sites. Still no changes.

Only plugin difference is the WP Language one which is on the French side only.

Are you sure there were no differences when you used diffchecker?

This is the English on the left: https://www.diffchecker.com/n2n4r5f1

On line 114 of that Diffchecker page, on the English source code you can see that there is a style which tells CSS that no border should be used, which is not there in the French version.

That is causing the top bar difference.

That’s a setting in the Customizr skin panel.

Hehehe!
Thanks! I thought I was going mad since I’d never added that border thing in my stylesheet!
Just read the english one again line by line and couldn’t find it anywhere! ??
