Search refiner web part stopped working after installation of CU

Bob Sieloff 1 Reputation point


We skipped the July CU for our SharePoint 2019 (on-prem) farm and installed the Aug 2021 CU's. We installed both the language independent and language dependent KB's. However we just realized that our search refiner web part is now broken with the following error:

Display Error: The display template had an error. You can correct it by fixing the template or by changing the display template used in either the Web Part properties or Result Types.

No included language files were loaded for locale (en-us) or the site's default language (en-us) for string ID (rf_RefinementAriaLabel_More). Please make sure you include the string IDs required by this Web Part in a language file that your Display Template references in the Site Collection Master Page Gallery. (LoadResource: )

A search on the net reveals that some people had problems after installing the July CU without installing the language dependent KB. Our error is similar but again we installed the Aug. CU and both KB's.

Anyone else see this issue or have an idea on how to resolve this one?
