Hi NOPTEMPLATES-team,

when creating a new product ribbon in the nopcommerce admin (V 4.52) backend saving with button "save and continue edit" the entry got saved, but displays the message "DataTables warning: table id=product-overrides-grid - Ajax error. For more information about this error, please see http://datatables.net/tn/7".

This is due to a call to url /Admin/ProductOverridesAdmin/ProductOverridesList?entityType=ProductRibbon&entityId=21 which returns a http error code 500.

The same happens when editing the entry and clicking on the same button.
The problem also occurs for QuickTabs plugin when saving.

The error only occurs when having distributed cache enabled in appsettings. I use MSSQL Server for caching.

Also happens with the last version of SevenSpikes.Nop.Plugins.ProductRibbons.dll (4.5.314.35608) and last version of SevenSpikes.Nop.Core.dll.

Error tracked in the error log is:
Object reference not set to an instance of an object.

System.NullReferenceException: Object reference not set to an instance of an object.
