Export all products error

-- url of the page with the problem -- : www.ifparts.com
-- HikaShop version -- : HikaShop Business 2.2.1
-- Joomla version -- : 2.5.11
-- PHP version -- : x.x.x
-- Browser(s) name and version -- : Chrome
-- Error-message(debug-mod must be tuned on) -- : Error_message

I have tried several times this morning to export all products.
But I receive the same error message each time:

www.ifparts.com/administrator/index.php?...ikashop&ctrl=product probeerde op te halen. De server kan offline zijn wegens onderhoud of kan onjuist zijn geconfigureerd.

Is there something wrong with the server?

Hi,

It's probably a resource issue. You should contact your hosting company and see that with them. Maybe they need to increase some limitations like the memory_limit or the max_execution_time of PHP.

Hello,

What should the limitations be according to you?

It depends. The more you have products/categories/etc on your website, the more they should be big.
Usually, 60 seconds of max execution time and 64M of memory limit should be enough.

Hello,

Memory limit is: 256mb
Max exe time is: 600.

And so what is the error listed in the PHP error log of the server ?
