server does not support remote connections

Unable to complete install and install
Your server does not support remote connections.
Please download Scientia Mobile DB-API Plugin manually,
install as any other Joomla! plugin.

Can't find where or how to install DB-API Plugin.

The link on error message just takes me to the MobileJoomla site.

I'm having the same problem. there is a solution if you are NOT running J1.5:

www.mobilejoomla.com/forum/15-install-a-uninstall/10155-download-scientia-mobile-db-api-plugin-manually.html

I am however running J1.5 and am unable to complete the install as a result. To the MobileJoomla tech support staff:

1. Is there a sceintia mobile plugin for J1.5?
2. If not, can you tell me what kind of "remote connection" my server isn't supporting, so I can remedy this from the server side?

thanks.
