Product deadline is in the past (presta Version 1.3.6.0)

[Azurafiles]

I attached the file because the code would be to long for the topic.
I get a error which says that the product deadline is in the past.

I set the product to expire on 2020-12-12, so should not be any issue there.
I also followed a guide here on the forum which many have used, but it still does not work for me.

Any clues?
Would be greatfull if someone could make this work for me.
I use batchdownload able products module.


Was reading this guide:

http://www.prestashop.com/forums/viewthread/61020/installing_prestashop/issue_with_prestashop_1_dot_3_dot_1_and_downloadable_products


But still no joy.
I can't find the File : settings.inc.php

They where talking about editing it with this:

define('DOWNLOAD_BY_REDIRECT', 'true');define('_PS_TEMP_DOWNLOAD_DIR_', 'full file path to a temp download directory modded 777 here');define('_PS_TEMP_DOWNLOAD_DIR_URL', 'full url to temp download directory modded 777 here'); 

get-file.php

I found this.

$product_deadline = strtotime($info['download_deadline']);
   if ($now > $product_deadline AND $info['download_deadline'] != '0000-00-00 00:00:00')
       displayError('The product deadline is in the past.');

Should I just delete this message?
I have a backup, but unsure if this is such a good idea


Edit: made no difference.
Any clues what could be the issue here?

That error message should only occur if the download has expired. Check the "Expiration date" of the download. It should be a date in the future.

having issue with this it says expires on 2289-12-31 18:00:00 downloadable 100 times but the system is saying 1969-23-18:00

I am receiving this error message, however, I show that I have set NO expiration date so why are my customers getting this message and how do I fix it?
