How to turn off error output in opencart 2?

Question

opencart

Worth opencart os 2.2. Installed pickpoint and sdek modules. With grief in half launched them both. They work with a bang. But they display errors in the header of the basket. Also worth a symbol. In the admin panel and the simple turned off the output of errors. But opencart ignores these instructions and further displays complaints about currency.php Can I write something somewhere in the files or delete it so that errors are simply not displayed?

Answer 1

At least you wrote what kind of mistakes.
Well, isn’t it better to fix these mistakes / hire a specialist who will do this? After all, messages do not just appear. Don't turn it off completely - log it at least...
