After a Parallels Plesk Panel (PP) upgrade,  I see a blank page when trying to open the control panel.
I also see this message in the event viewer:
PHP Startup: Unable to load dynamic library 'C:\Program Files\SWsoft\Plesk\admin\modules\php_curl.dll' - Access is denied.


The reason for this issue may be that incorrect permissions are set for PP folders.


1.      Add full permissions for the psaadm user on C:\Program Files\SWsoft\Plesk\admin\repository;
2.       Make sure that permissions for C:\Program Files\SWsoft\Plesk\admin\modules are the same as shown below:
