Exception #0 (Exception): Notice: Array to string conversion in /var/www/html/Magento-CE-2.1.9/vendor/magento/framework/Phrase.php on line 69

When I disable the module everything works perfect. Can anyone please let me how can I resolve this. I am using PHP Version 7.0.25 and Magento version 2.1.9

Answer 1

I know that this is old, but in my case i had the same problem and reach this issue here . It was an error in my system.xml payment method file, where i put the tag on a wrong place. So this problem can be a system.xml file with wrong configurations.

Answer 2

My code snippet is from Magento 2.2 and things are more strict in Magento 2. Here it states clearly that you need to pass an array when you make an instance of the class.

.../framework/Phrase.php:69
public function __construct($text, array $arguments = [])

Or maybe you should develop your code in smaller steps. First use a generator to get a working framework for a module, like: https://mage2gen.com/ Then add your custom code bit by bit and when it fails, then you know where the error is.
