PHP Notice:  Trying to access array offset on value of type null in Sources/Load.php on line 3130
PHP Stack trace:

5. loadLanguage($template_name = 'index+Modifications', $lang = *uninitialized*, $fatal = *uninitialized*, $force_reload = *uninitialized*) Sources/ScheduledTasks.php:1042
The 'template' argument is being given to sprintf(), but should be given to log_error().
