Hi,
I consistently have problems upgrading wordpress and plugins. I also have trouble installing new themes and plugins.
The message is usually "cannot create directory/path". Sometimes it completely shuts down for "maintenance" when I am trying to install or upgrade.
My wordpress url: http://ladystrength.com/wp-admin/
Not sure if this is a hosting issue or wordpress issue but I have been having this trouble for quite some time now.
Thanks!
Rebecca
