Hi Jose, did you get any help on your blog question?
I've done a bit with Wordpress over the years, not the most experienced person, but I've had a few blogs.
Was this Wordpress update done through the Wordpress platform, or through GDI? I did notice that on GDI's website on the page that talks about the plugins that there are some issues with doing the Wordpress updates, likely you noticed that too.
To quote from their site...
"It has been brought to our attention that members who attempt to upgrade their WordPress blog from within their WordPress interface using the automated option are encountering issues with their websites and/or their WordPress login pages not displaying properly. Our technicians are working on a implementing a possible fix. We ask that current members refrain from upgrading their WordPress blogs using the automated option in order to avoid possible issues with their WordPress blogs. If you would like to upgrade your WordPress blog to the latest version, you may still do so via FTP. For instructions on how to go about updating your blog manually, please visit

Thanks
