I have a custom path for my wp-content folder, which is something that is supported by WP. But unfortunately it doesnt appear that your plugin correctl handles it. when i go to install a plugin, i get an error (this is before i even start it):
Warning : The folder /home/username/public_html//home/username/public_html/site_content/plugins/ must be writable by PHP for the plugin installer to work. See Changing File Permissions for a general guide on how to fix this.
I use suPHP, so all folders/files are obviously already writable. Its just getting the path messed up as you can see. Any ideas? I absolutely love your plugin.
