I installed on a hosted site. I checked all the things listed in the installation doc and everything checks out, all the files and database tables where they should be, but when I try to add the module to a page I get the following error:

Unhandled error loading module.

My DNN installation and the DMX install have both created lots of folders on the site so I'm not sure why I'd be getting this error?

One thing to add in case it is relevant - I didn't create my portal folder in the default location as a numbered folder below Portals, I used a custom location. The custom folder I specified was created and the standard files and the Templates and Cache folders were created in the Portal folder.

OK, so I just tried to add the module in the host portal, which is located in the regular location (Portals/0) and it worked. So is there a known issue with using the module in portals that use a custom Home Directory? I'll create a new portal in the default location if I need to, but if I can make it work with my current portal that would be nice.

Thanks
Sean

I have managed to get this working - the custom portal directory for my portal had a slash (/) at the beginning of its name. I updated that directly in the database (its not editable through the DNN admin) and removed the leading slash. Now it seems to be working fine. This is something that DMX and probably DNN itself needs to handle a bit better I guess.
