I am experiencing the same issues as well.

Are there any further permissions which need to be granted, and if so, to which user?

I to am having the same problem... Is there any idea of why this happens??? what to do?

I did not have this problem on Godaddy (had other problems there like building PDF's and full trust)
So I switched to Softsyshosting.com (Recommended by Skiltz)
So what is the deal with not being able to edit Product?? Is there a DB setting I need to change or a file setting?
- Microsoft SQL Server 2008
- ASP.NET (1.1 / 2.0 / 3.5 SP1)
- IIS 7

Any help?
Shane

sweddle.  send a email support ticket softsyshosting and ask "can you please change my website to full trust".  This will sort you out.  They should do it in a matter of minutes.

Thanks,
Matthew

The same apply to all others in this thread.  Make sure you are running full trust.

Hi Matthew (Skiltz),

Thanks for the info on SoftSys. I like them allot so far. much much better and faster then GD.
I told them that you referred me and I have senses then referred another client to them.

Thanks for the help hope the full trust thing works.
Shane

Yes their support is friendly and fast.  Let me know if that fixes your issue.

Woohoo! Yes that fixed it and Ya they are supper fast!!!

Only odd thing is this:... on Godaddy I could not have NopCommerce build/make PDF invoices do to a lack of full trust (one of the reasons I left them.. one of many) but i could edit product leading me to think I was able to edit in Mid trust...
It’s no biggie nor a complaint just an interesting observation and who knows with GD there hosting is so half hazard it could be any number of problems...

SoftSysHosting is really doing a good job!
Thanks Skiltz!
