I have written a replacement SmallSearchInputBox packaged as a feature and this has been working fine on the test server. VS2010 is also installed on the test server and I have been able to deploy directly from VS2010.
I now want to set up the production server. I took the WSP from the VS release folder and installed it on the prod server using Power Shell - Add, Install etc. I activated the feature but no search box is visible - no even the standard search box. I have set the logs & traces to verbose but there is not mention of search at all.
I pulled up the master page in the Sharepoint designer and was surprised to see my replacement search box displayed in the preview!
What might be going on here? My feature seems to be active but somehow is not being displayed. Has the search been deactivated for some reason? How could I check?
