I am running the CoursePress plugin. I put the Search box code and Results code for Google Custom Search (not the plugin) into two (separate) pages.
The results do not show. Instead, this displays on the results page
"No Courses Found
Sorry, but nothing matched your search terms. Please try again with some different keywords."
The results page has Google's code for displaying its search results. Yet there are no Google search results, and the above message is displayed.
