Having an issue with my Search Results module after an upgrade from DNN 7 -> DNN 9.2.2
Everytime I search using DNN's Xcillion (built in search) I keep getting "A critical error has occurred. Please check the Event Viewer for further details." (/Default.aspx?tabid=87&error=Object+reference+not+set+to+an+instance+of+an+object.&content=0) error on the search results page.
I have tried to re-index via deleting content in search folder i.e https://dnnsupport.dnnsoftware.com/hc/en-us/articles/360004881174-Search-Not-Showing-Expected-Results
have backed up old files from /desktopmodules/admin/searchresults and added in fresh ones incase something went wrong during installation, same with DLL files that might effect the search to no avil.
Any hints or ideas would be awesome, everything else works correctly on this instance of DNN just cant figure this error out.
