Good morning
I sent you the login - did you receive it?
Thanks...

Hello

I dont see the suggested CSS in your source code. If you have multiple template styles, try adding the suggested CSS to each style. If not, may I suggest sending temporary administration access to your Joomla installation to info@joomla51.com and we will examine this issue further. For our reference please paste a link to this post in your email.

Good morning,
I've tried this, but it does not work. The strange thing is, that the color was different before I installed a newer version of the template.
Thank you.

Hello

To amend try adding the following to the Custom CSS field of your templates parameters (Extensions -> Templates -> [YourTemplateStyle] -> Custom CSS)....

.menu-toggle span, .menu-toggle span:after, .menu-toggle span:before {

    background-color: white;

}

the hamburger is a fontawesome v5 icon, so you can't change the colour

hi
thank you, that didn't help. i added the link.

For design questions you always need a link to the problem.
Try inserting the following code in your template styles under: Custom CSS:

.slicknav_menu .slicknav_icon-bar {



  background: rgba(255, 255, 255, 0.7);

}
