If you manually go to your page
https://www.fanmats.com/coastal-carolina-soccer-ball
do you then get the any errors logged?

Did you make any custom changes to Nop.Plugin.Tax.FixedOrByCountryStateZip?

Hi,
Thank you so much for reply.
I wan haven't made why changes to that recently.
But before i have uninstalled and reinstalled the plugin, and currently a 0% tax is set for one state. No other entries are there.
Should i remove that entry ?

Sorry forgot to answer that part of the question.
No i do not get the error then.
This error starts randomly and it goes to construction page.
I have a hunch that it starts off i change banner or static content. Especially since the only recent setting change i made was enable different cacheing options via iis7

Also my nopcommerce version is 4.10

What version of SQL server are you using?

See this post

Thank you new york, i think you are probably right. I am indeed using only SQL Server 2008R2. Therefore had to enable UseRowNumberForPaging=true to get backward compatibility.

I guess the only option is to upgrade to latest version of SQL to solve issue.

But thank you very much for taking your time to help me with this. Really appreciate it.
