Can you please share a link to the pages where the search is not functioning?
I see in the shortcode that you are limiting the results to entries to those only in category 2 … when you test searching, you are searching only for entries that are assigned to category 2, correct? I ask because only entries assigned to category 2 will be searched for.
The view more link, so to speak … click on the entry name, that links to the single entry view in cMap. This does not exist for Slim Plus though.
