On local iis server everything is ok.

Seems that something got wrong during installation ('Guests' role awsn't inserted). Try to reinstall the application (and clear the database before it's done)

Db update helps. But now a have new problem

Admin workin fine!
Frontend, until I try to open any page where is product data.

i got an error.

Have a look at the following topic https://www.nopcommerce.com/boards/t/10664/nop-2-fresh-install-object-reference-not-set-to-an-instance-of-an-object.aspx

As I understand the main point is the https://www.nopcommerce.com/boards/t/10500/publishing-20.aspx link.

I tryed to do everything as described, exept deployment useng WebMatrix.

The steps was:

1. Download source
2. Open it in VS 2010
3. Run project and install NopCommerce on local DB (copy of server DB)
4. Executed Update SQLs
5. Everything work fine! (Admin and frontend)
6. Rebuild application with new sqlconnection sting (Hosting SQL server)
7. Test ok!
9. Run Prepare.bat (no errors)
10. Run Deploy.bat (no errors)
11. Copy all files from \Deployable\nop_2.0\ to the Web server
12. Copy DB From local station to Web SQL server
Open site, it opens, everything looks like ok, but when click on product/category/manufacturer i get this error.

Can you please tell me where is my mistake?
As I understand from the link you give me before, i do everything right.

Seem that you didn't deploy plugins (Tax provider plugin can't be loaded)

wwwroot/plugin folder isn't empty

i compared it with the folder from nopcom...2.0_noSource.zip.

they are similar

Open \App_Data\InstalledPlugins.txt file. Is it empty?

I dont have such file in this folder (on web server).

But in the source folder it contains:

DiscountRequirement.BillingCountryIs
DiscountRequirement.PurchasedAllProducts
DiscountRequirement.PurchasedOneProduct
DiscountRequirement.HadSpentAmount
DiscountRequirement.HasAllProducts
DiscountRequirement.HasOneProduct
DiscountRequirement.MustBeAssignedToCustomerRole
DiscountRequirement.ShippingCountryIs
CurrencyExchange.ECB
CurrencyExchange.MoneyConverter
LiveChat.LivePerson
Payments.CashOnDelivery
Payments.CheckMoneyOrder
Payments.AuthorizeNet
Payments.Manual
Payments.PayPalDirect
Payments.GoogleCheckout
Payments.PayInStore
Payments.PayPalStandard
Payments.PurchaseOrder
PromotionFeed.Become
PromotionFeed.Froogle
PromotionFeed.PriceGrabber
Shipping.AustraliaPost
Shipping.CanadaPost
Shipping.FedEx
Shipping.FixedRate
Shipping.ByWeight
Shipping.UPS
Shipping.USPS
Mobile.SMS.Clickatell
Mobile.SMS.Verizon
Tax.FixedRate
Tax.FreeTaxRate
Tax.StrikeIron.Basic
Tax.CountryStateZip


That means that build was unsuccesful? What should i do?

It means that you didn't deploy nopCommerce properly. This file is created during installation and contains a list of installation plugins. Just copy it to the server and restart the applciation
