How to Solve the Message ‘Character Content Other Than Whitespace’ in Magento 2

adminemailmagento2module

I've received that message below when I try to reset my admin password using the Admin panel, I've my custom module installed.

I see this same message on a white screen when I try to access using the tab created in System > Configuration.

Message:

Invalid XML in file /var/www/html/rmiorder/app/code/Vendor/Hosebuilder/etc/email_templates.xml: Element 'config': Character content other than whitespace is not allowed because the content type is 'element-only'. Line: 2

File XML:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Email:etc/email_templates.xsd">
    <template id="vendor_hosebuilder_section_general_show_email_template" label="Hose email template for requesting quote" file="hose_request_email_template.html" type="html" module="Vendor_Hosebuilder" area="frontend"/>
</config>

How can I solve that issue?

This problem you got because the XML code, you copy directly on internet/webpage, there is some hidden character before start each line. This isn't space/ newline character. So, when push to Magento, Magento doesn't know this character, and it shows errors as your message. Solutions: clear all space between tag and order again.

Magento2 Module – Fix ‘main.CRITICAL: Plugin Class Doesn’t Exist’

I couldn't reproduce your error, but I got an other one.

Then I did some minor adjustments to your code and it worked.
First drop the InstallSchema.php file. It does nothing so it is useless.

Then make sure that your plugin file is in Amaj/CorePlugin/Model/Currency/Plugin.php and it looks like this:

<?php

namespace Amaj\CorePlugin\Model\Currency;

class Plugin
{
    protected $logger;

    public function __construct(\Psr\Log\LoggerInterface $logger) {
        $this->logger = $logger;
    }

    /**
     * @param $subject
     * @param \Closure $proceed
     * @param $price
     * @param array $options
     * @return string
     */
    public function aroundFormatTxt(
        $subject,
        \Closure $proceed,
        $price,
        $options = []
    )
    {
        $this->logger->info('Amaj aroundFormatTxt');
        return '2';
    }

}

you don't need parent::__construct(); in the constructor because there is no parent class.
And I replaced $logger->info with $this->logger->info because there is no $logger variable.
