Ok, now I understand.
The logos on my site do not have review links but affiliate links, because no url has been added in the settings, so I will find out now. So you always have to provide a link for reviews! This is perhaps something for an update to the theme: there are users who do not always want to create reviews 🙂
I will, in any case, create reviews in a few weeks.
So specify an asterisk #? Or something else for now?
The size is 1920×501. The image does not have to be that much sharper, but lighter, now it is much too dark. The header image is too dark on mobile devices and Ipads. Is there a piece of code for this to adjust the contrast or to apply a certain setting?
