To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2017-10-13 20:28:33] stefan dot beyer at xornet dot de Typo: I meant "REDAXO CMS" ------------------------------------------------------------------------ [2017-10-13 20:11:26] stefan dot beyer at xornet dot de Description: ------------ PHP crashes when running REDOX CMS in built-in server.
