I've made some tests to solve this problem: trying to update some plugins via Wordpress backend I always receive a "Unable to create folder" error.
So I've initially added IIS_IUSRS
with Read/Write/Modify permissions (not full control), but nothing changed.
Then I've tried to add IIS_IUSRS
with full control, but I did not solve.
My final try was to add "Everyone
" user and give him the Read/Write/Modify permissions. And it works!
But do you think it's a security hole to give this permissions to Everyone user? And what do you think could be a solution?
I'm using: Windows Server 2012, Wordpress 4.0.1, PHP 5.4.24, IIS 8.0
