myDEBUG Backtrace [Support Thread]

[lat9]

Well... it's the reason! The parameter was introduced in PHP 5.3.6.

You can edit the /includes/extra_configures/enable_error_logging.php file and its admin counterpart, changing the line that reads:

  debug_print_backtrace (DEBUG_BACKTRACE_IGNORE_ARGS);

to

  debug_print_backtrace ();
