I am running Apache 2.4.23 and PHP 5.6. Everything runs fine except a PHP script that is being silently dropped in the middle of its execution at a specific spot.
"display_errors" are On and error_reporting is set to E_ALL in php-5.6.ini. I have multiple error_log statement that I use as a trace to determine where execution stops and now surrounded the section in question with a try/catch that would do an error_log with the exception, but again only silence, both in Apache's error_log and php_error.log.
Max execution time and memory limit were already raised to twice the amount as per default and each error_log prints microtime() along with it, showing that the script is executed within a single second.
SOLUTION: VQMOD was interferring with Woocart, in particular with the parts of the code that Apache stopped from execution. After removing the corresponding VQMOD XML files it all ran fine again.
