I am using latest free version of js jobs. When i try to do a job search its showing "Couldn't find any matching results" though there is jobs listed uder the particular category .
check in your data base under "js_job_jobs" and select any job created, then check the date of this field "stoppublishing ". By default, you could get 1970.01.01, if you change it, you'll see your job online.
