/admin/SmartSEO/Configure = 404

Hi there,

We just purchased a license for Smart SEO. The plugins (Core and Smart SEO) appear to have installed successfully (registered in the plugins list, activated properly).

But when we go to Plugins > Nop Smart SEO > Settings, there is a 404 trying to find the file path.

This is for NopCommerce 2.8.

Please advise.

Hi jianni,

Can you try adding a few empty spaces in your Global.asax file (as described here)?

Thanks

Hi Boyko,

Thanks for your reply. This was attempted. But we still get a server error on plugin activation (this is after restarting the application and clearing the cache).

Here is the Stack trace:

I see in the stack that it reaches the SevenSpike plugin and it is tries to register the route when it gets a null pointer to an object. Seems to me there's an error in the code somewhere.

Hi jianni,

If the Core and the SEO plugins are installed then the problem might be related to some third-party plugin you are using or any modifications you have made to nopCommerce.
Have you removed the Admin_Default route in nopCommerce or do you have any plugins installed that remove the Admin_default route in nopCommerce?

Thanks

If you have ever received a message from Windows like
Cannot delete file: Access is denied
There has been a sharing violation.
The source or destination file may be in use.
The file is in use by another program or user.
Make sure the disk is not full or write-protected and that the file is
not currently in use.
Error Deleting File or Folder

when you tried to delete, move or rename a file, then this program
will be helpful. Path Too Long Utility identifies the processes

being deleted, moved or renamed.

I gave up on fixing the issue a while ago. We just finished a server move and thought it might have fixed the problem because other plug ins were not functioning. I have reviewed our source code and disabled all of the other plug ins beside the core and SEO and we still have issues. We still have the Admin route you described.

What else could be the issue?

Found the issue. In Nop 2.8 (or at least our version), the "Admin_Default" route is written "Admin_default". I guess it could not find the route in the collection.
