Hi Daniel,
If you want to configure the all authors page, you would have to create a menu item for this page since there are settings that you can configure there: http://take.ms/HRtWc

no i dont want to have displayed any informations about the bloggers.

Hey Daniel,
Are you referring to information like author biography, Twitter and website?
Or do you mean that you do NOT want to allow users to access to this page?

yes.

Hey Daniel,
You can try creating a menu item that restricts access to the authors page: http://take.ms/XTatX

thats not a good solution.
A menu item which is displayed in the menu???

Is there no solution in the EasyBlog admin to deactivate this?

There is currently no settings to disable this feature altogether because to be honest, until today, nobody has actually requested to hide this page.

If you want to disable this, you can add the codes below into /components/com_easyblog/views/blogger/view.html.php and at line 33 add the codes below,

[gist]
$this->app->redirect(EBR::_('index.php?option=com_easyblog', false));
[/gist]

This will enforce anyone who tries to access the blogger's page manually by typing in the url.

Hey Daniel,
The menu item can be hidden when you place it under a hidden menu: http://take.ms/s4Om2

Is there no solution in the EasyBlog admin to deactivate this?

There is no setting to disable this page.

is it possible to change the code in EasyBlog admin or only by open file per ftp?

Hey Daniel,
You can try the redirection code mentioned by Mark above.

is it possible to change the code in EasyBlog admin or only by open file per ftp?

Hey Daniel,
If you are referring to editing the theme files in EB backend, then the answer is no because this is not a theme file.
Therefore, you have to edit this by opening the file. As a reminder, the changes in this file are not protected by future updates.

yes i know.
But is it possible to have in a next update these function in admin?

Hey Daniel,
We have no plans to implement this. Do note that there are other ways to set up redirection on your site. Other than 3rd party components, using htaccess is another way to do so: https://docs.joomla.org/Creating_301_redirects
