Hi Valentin,
You should use English when submitting a post as we do not understand your language.
From your screenshots, it seems you have an css issue. Can you try to use the custom css codes below and apply in the following directory(create directory and file if they do not exist): JoomlaFolder/templates/yourCurrentTemplate/html/com_easyblog/styles/custom.css

div#fd.eb .eb-entry-author-meta span a {

    color: #f77450;

}

Ok thanks to you it works
