I am ssing WP 2.7 installed on a Mac Mini.
I have seen topics similar to this, but none with resolutions that have worked for me. When trying to use WP's automatic upgrade plugin feature, I get the following error message
Unable to locate WordPress Plugin directory.
Plugin upgrade Failed
I have tried using a user account with home directory of WP's root (on the Mac from which this is served, this is /Library/Webserver/Documents). I also have tried with a home directory of /Library/Webserver/Documents/blog (the WordPress address where WP is actually installed on my webserver). When testing with an ftp client (cyberduck), I drop directly into the folder specified as the user's home.
There is nothing non-standard about my installation, as far as I can tell - the plug-in directory resides in its default location, within wp-content.
I do not encounter any authentication issues - just the error that the plugin directory cannot be found. Any help will be greatly appreciated.
