System.Exception: Plugin 'Must be assigned to customer role'. Access to the path '..' is denied.

I have been working on nopCommerece 4.10 for the last couple of weeks on my local machine. it was working fine. Today, when I tried to deploy it on the server (for that I am using smarterasp.net hosting) it is not working. everything is there, DB, files etc.

here is the error log.

Application startup exception: System.Exception: Plugin 'Must be assigned to customer role'. Access to the path 'h:\root\home\anir22-001\www\excell\Plugins\bin\Nop.Plugin.DiscountRules.CustomerRoles.dll' is denied.

Sounds like a 32-bit / 64-bit conflict on the server.

I would suggest contacting your hosting provider.

Just encountered the same error message. I do not advocate this for a live site but for the time being to get the dev site up an running go to the website folder (but do not click into it) and set security permissions to Everyone = Full Control.

So for example if your NOPCOMMERCE dev site is

C:\Inetpub\Websites\NOPCOMMERCE

Right click NOPCOMMERCE, select Properties, select Security, Click Add, Type Everyone, Click OK, Select Full Control for everyone, Click Ok, Click OK.

Restart your NOPCOMMERCE web site (IIS -> Right CLick the NOPCOMMERCE site -> Restart)

Site will start to work.

My guess is (at the moment I am not looking into it as I'm busy setting the site up) that the account that the Application Pool runs under most likely needs to modify rights.

edited to add:

If using a hosted provider you may need to create an account for the app pool and then give that the correct file permissions. If you using a shared app pool.. find another provider.

Another thing you might try is the option in appsettings.json to turn shadow copy off
