wp-admin：对不起，您不能访问此页面 - Wordpress

Question

So im having some problems to login after tranfer from Windows hosting to Unix.

When im trying to login to admin panel i see this:

Sorry, you are not allowed to access this page

I have used google, search and etc. All what was written in posts doing for me nothing, like disable plugins, change theme and so on, im still having this problem. I have asked hosting company, they have told me this:

The problem is caused by the fact that you created multisite and most likely made confusion in the privileges. You'd better turn to the wordpress programmer

But the thing is that i have not created multisite, only installed the language plugin(WPML).

DEBUG and error showing me nothing.

Answer 1

This is basically permission issue.

You need to do the following,

find foldername -type d -exec chmod 755 {} \;
find foldername -type f -exec chmod 644 {} \;

Change the files permission to correct ones , 644 for files and 755 for folders.

Answer 2

编辑current_user_can函数是/var/www/html/wp-includes/capabilities.php并添加if（is_admin（））返回true;
