The Jobs Expire Time (Days) setting on the Configuration Options page in the Jobs Portal administration panel allows you to set the number of days in which the jobs posted on the website by the employers will expire.
The expired jobs stop showing on the main site, when making searches or browsing the categories and they only show up on the Expired Jobs tab in the employer admin panel, so the employers can select to renew them.
The expire time of the jobs should be set in days - the default value is 30 (meaning the posted ads will expire in 30 days), but you can easily change it with another number of days you may prefer.
If you set it to: -1 , then the job ads posted on the website will never expire. Also if you have previously expired jobs and set the value to -1, this will make again all jobs to show up on the website.
