Internal server error on specific storeview

[magentomarcel]

I am running a Magento multistore and recently upgraded to 1.9.2.4. Strange issue arose: With certain configurable products I get an internal server error upon cart placement, and this only in one domain/storeview.

This is the error I get in my server logs:

[Fri Jul 15 16:07:29 2016] [error] [client 83.83.80.192] FastCGI: incomplete headers (0 bytes) received from server "/dev/shm/izinqcom-php.fcgi", referer:http://www.wimperwensen.com/godefroy-instant-eyebrow-tint.html [Fri Jul 15 16:07:29 2016] [error] [client 83.83.80.192] (104)Connection reset by peer: FastCGI: comm with server "/dev/shm/izinqcom-php.fcgi" aborted: read failed, referer:http://www.wimperwensen.com/godefroy-instant-eyebrow-tint.html

Since it only happens with one storeview and not all configurable products I am completely in the dark as to why this happens.

Any suggestions welcome!

Greetings, Marcel

Could you please turn on error in magento to see errors on page:

How to enable show error in magento:

1. Edit index.php

2. Search for below code

if (isset($_SERVER['MAGE_IS_DEVELOPER_MODE'])) {
   Mage::setIsDeveloperMode(true);
}

3. Replace it with

//if (isset($_SERVER['MAGE_IS_DEVELOPER_MODE'])) {
   Mage::setIsDeveloperMode(true);
//}

4. Now search for 

#ini_set('display_errors', 1);

5. Replace it with 

ini_set('display_errors', 1);

Hello,

Thank you, I did that but the no errors are shown because the internal server error page is triggered on the server, not the magento root.
