I've successfully installed and configured my site, but I can't install modules or themes. I've tried several times to install one from the gallery but I get the following error:
Package installation failed.
There was an error installing the requested package. This can happen if the server does not have write access to the '~/Modules' or '~/Themes' folder of the web site. If the site is running in shared hosted environement, adding write access to these folders
sometimes needs to be done manually through the Hoster control panel. Once Themes and Modules have been installed, it is recommended to remove write access to these folders.
Request for the permission of type 'System.Net.WebPermission, System, Version=188.8.131.52, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I've used the GoDaddy file manager and set permissions on every single file/folder on my site, but I still get that error. I've tried deleting and recopying, but it doesn't help. I even had GoDaddy check the file permissions directly on the server
but they say that they are all write-able as they should be. What else could cause this error?
