NopCommerce Application error

I am using NopCommerce 2.65 and all of a sudden when adding new products to my store I am getting an application error. I tried a couple of products and the error happened every time. It has been a few weeks since I added any products, but this did not happen before.

Here is a copy of the error that I received on the last product I was trying to add...

Thanks for the reply Rum, I have tried both letters and numbers. I am just trying to add a new product to the database and am getting this error. I have been adding products and updating for weeks without any issues. The only field that I was trying was the new product name field and anytime I try this I am getting the error. I had posted a message for Winhost support and they think that it could be an issue in that I am using sql server express instead of a full version of sql server. I checked the Nop site and they say that it is ok to use a sql server express db.

 

Hi Rum,

Ticket Number 237-18340B69-02A5

Thanks!

 

Hi Rum, I just wanted to see if you were able to figure anything out or make any progress on a solution on how to fix the issue.

Thanks

 

It looks like we answered your ticket this morning. We can't find any server-related cause for the error, so you'll have to check with NopCommerce for a possible cause/fix.
