I have installed a few Word Press sites using WPI. These sites can install/ update new themes and modules but won't update the Word Press Core and always result in the error:
"Downloading update from https://downloads.wordpress.org/release/wordpress-4.1-new-bundled.zip…
Unpacking the update…
The update cannot be installed because we will be unable to copy some files. This is usually due to inconsistent file permissions.: wp-admin/includes/update-core.php
Installation Failed"
I have tried giving the AppPool ID Modify and then Full permissions over the entire site but this hasn't fixed this.
How can IIS be configured to allow this?
Is this a big security risk?
TIA
