Hi,
thank you for your response. I figured out the problem myself. The problem was with the DomainMapping Plugin.

Since I have a multisite installation, I wanted to map certain sites to certain domains.
For example in this case the initial Site URL was:
https://wordpress.gartenhaus-wohnkultur.de/wohnkultur-cane-line/
and it was mapped to https://die-exklusiven-gartenm?bel.de
I mapped the URL correctly with the plugin, however I forgot to change the site URL from wordpress.gartenhaus-wohnkultur.de/wohnkultur-cane-line/ to https://die-exklusiven-gartenm?bel.de

Therefore the files on the homepage were served through the old url and not the new one, so it was:
https://wordpress.gartenhaus-wohnkultur.de/wohnkultur-cane-line/wp-content/uploads/sites/7/2016/06/Slider_Conic_01.png

and not
https://die-exklusiven-gartenm?bel.de/wp-content/uploads/sites/7/2016/06/Slider_Conic_01.png
as it was supposed to be.

I as well had to change the URL with certain plugins, in my case the Huge IT Slider, since some urls for media were not changed automatically with the site url.

After that, the plugin worked correctly.

Now I cannot generate Packing Slips as well, so it seems it has something to do with my server settings.

If you apply the code

<div id="main" class="wrapper" style="background-color: white;">

you can get an idea what I want to.

I would like to have the widget area and the area around as well in white.

Chech it here:
https://praepkurs-tms.de/lernplan-tms/

Now the article area is white.

Actually, it’s not. If I would aplly it to the div under the body, the header changes as well. I only want to change the widget, the article area and the area around it.

If I add in:
<div id="main" class="wrapper">

a custom css tag, it works:

<div id="main" class="wrapper" style="background-color: white;">

However if I change the wrapper in the css it doesn’t.

Any idea where I can change this div tag, in which .php i can find it? Or any better solutions?

I am using firebug. Are there any problems with that?

Ok, thanks for the response =)
