the cron is scheduled to run every 10 mins so it is possible to get more than one PM per ad

lol well atleast its pm's not emails

PM said that the ad was deleted, but in fact, the ad is still active. What exactly the cron job does?

Another issue: I can't set ads to be premium. I check the box, but the item doesn't show as premium, and in database "premium" field is set to "0". Is this a bug, or it has to be enabled somewhere else?

I think, in microclassifieds_cron.php line 194 should be:

$timenow = time() - $grace_period; (currently $timenow = time() + $grace_period; )

Otherwise, it will try to delete ads that have not ended yet.

What has this file in difference Mike?

both lines 1401 and 1619 should have the microclassifieds/datagrid removed from between the ' '
should look like this
$objGrid -> language(' '.$vbulletin->options["microclassifieds_grid_langcode"].'');

Same thing for me with the PMs and had to disable the cron job as there were 100s of PMs. What's the best way to fix this?

Try using that file chris uploaded for me to change the expiration date of all the ads.

just remember to change the value to the number of days that you want before it expires

Thanks Mike and Chris, that seems to have worked with the expiration dates. I must have missed that post.
