I set auto-reupublish feature , i post a listing with this feature the listing has been expired but no auto republish why?

@Adrian Rus
If it does not work, that means cron on your site does not work. You should contact your hosting provider to help you setup cron for osclass.
You can find what do do also on osclass docs:
https://doc.osclass.org/Cron

Please do not use built-in cron on live website, it usually does not work reliable.

cron work because i recive the email with expiration but auto no work..

@Adrian Rus
You can find function bo_mgr_control_listings() that handles most of functions including auto-republish.
Call this function manually, i.e. placing to main.php of theme and then refresh homepage.
If there are listings that should be republished and were republished, then cron is not working.
