 * Hello,
 * We are facing an issue with accessing only /wp/wp-admin/plugins.php and wp-admin/
   update-core.php. All other links are loading fine. This is shared server – CloudLinux
   Server release 6.8 and the issue is not only for a particular domain. Every wordpress
   sites in the server is facing the issue.
 * The only error log available is “Premature end of script headers: cgi_wrapper,
   referer: [http://domain.tld/wp/wp-admin/index.php&#8221](http://domain.tld/wp/wp-admin/index.php&#8221);
 * We have tried with the following
    =========== 1. checked with the php handlers
   in the server and tried changing it from Apache, cgi and fast-cgi options. 2.
   Confirmed that there is enough memory in the server. 3.Checked with the files
   and folder permissions. 4.Backed up plugins and themes and then tried loading
   the link. 5.Tried loading the links after reconfiguring the domain. 6. increases
   the PHP memory limit. ===========
 * But still the issue persists.
    FYI :recently an Os update was performed in the
   server. The issue is not only with a specific wordpress version.
 * Any fix or suggestions?
