Upgrade to wordpress seem to be difficult for such conditions :
- Self hosted wordpress in shared hosting.
- Self hosted wordpress ( free hosting)
- Self server with little memory
I face few problem when doing wordpress upgrade.
In this case ” You don’t have sufficient permission to access this page ”
Upgrade WordPress
Downloading update from http://wordpress.org/wordpress-2.8.3.zip.
Unpacking the update.
Verifying the unpacked filese
Installing the latest version
Upgrading database
WordPress upgraded successfully
That message display when upgrade process went smooth, but when something wrong like insufficient memory that might happen in shared hosting I choose to do in old way : WPAU way.
