The controller for path '/' was not found or does not implement IController.

I recently migrated my NopCommerce sites to a new server. Originally the sites were located on the C: drive, now they are on the D: drive.

Ever since I migrated I can no longer use the Nop Ajax Cart plugin. It is giving me de volgende error:

The controller for path '/' was not found or does not implement IController.

I worked well on the original server but nog longer on the new server. The other Nop plugins still work fine.

Please double check if the Ajax Cat plugin is copied into the Plugins folder of your new installation. Also double check if the AjaxCart is present in the InstalledPlugins.txt file.
If they are present then you probably need to add a few empty spaces in your Global.asax.

Insert spaces in my Global.asax work for me!

Thanks!
