I don't know what is this error for. Can anyone explain it please?

[20-Nov-2017 17:20:53 UTC] PHP Warning:  Module 'apcu' already loaded in Unknown on line 0

Apcu is a php module used for caching opcode. http://php.net/manual/en/intro.apcu.php This means that it can help your site run faster. That isn't actually an error. It's a warning which means it isn't critical and it isn't actually causing any issues. It's just warning you that the apcu module was already loaded once in your code, and then your code tried to load it again. Maybe you have the same line duplicated in two places. The warning just lets you know about it so you can fix it if you want to.
