Do we miss any configuration

What is the version of nopCommerce 3.8 that you are using?

The first 3.8 was released with a critical performance issue so at 22 August they have released a new fixed version.

If you are using the "old" version it is not compatible with our products version 21801 or higher.

You can find out more information here.

We are using NopUltimateThemeCollection_3.8.648.22498 (NopBrooklynTheme)

Hi

I have made some further investigations and have found some common error patterns. It looks like the error is originating from nopCommerce, so I downloaded the lastes 3.80 with bugfixes, and the problem with searching is now solved.
