I am trying to install one plugin and update another in WordPress (not the one-click install version). Whenever I do this, I get the following error:
Downloading install package from http://downloads.wordpress.org/plugin/stats.1.8.2.zip…
Unpacking the package…
Could not create directory. /home/username/mysite.com/wp-content/upgrade/stats.tmp/stats
I have made sure the /wp-content directory and sub-directories have the correct permissions (755) and that the /wp-content/upgrade directory exists. I've even tried to manually create the stats.tmp and ./stats directories, but I get the same error and then the install script deletes those manually-created directories.
Any ideas on what the problem might be? I have the latest version of WP installed, and have also tried changing PHP from 5.2 to 5.3 (FastCGI) via the DH webpanel.
Thanks for your help.
