An unhandled exception occurred while processing the request

Hi all,

My NopCommerce 4.1 site crashed. I have attached the error from the log below.
I restarted the application and the website was up & running okay.

Any ideas on cause of issue and a fix so it does not happen again?

Kind regards,
Joe

Maybe this
https://www.nopcommerce.com/boards/t/54586/410-not-running-on-local-system.aspx#209684

Yes, that was the issue.
"UseRowNumberForPaging" needs to be set to "true" in appsettings.json if using SQL Server 2008 R2

I spoke too soon....


My Nopcommerce 4.0 site crashes intermittently.
I get an "An error occured while starting the application" message when I try to browse the site.

When I go to the server and restart the application it then browses okay.

When I check the error log I see the below:
Note: when I got this error previously I changed "UseRowNumberForPaging" to true in my appsettings.json file as I am using SQL Server 2008R2. However the site is still crashing.

Any ideas????
