Invalid system.xml file

[jahicDario]

I installed module, run all post-installation commands and when I login to admin page and try to go to Stores-Configurations I get this error:
1 exception(s): Exception #0 (Magento\Framework\Exception\LocalizedException): Invalid XML in file /.../app/code/bitExpert/ForceCustomerLogin/etc/adminhtml/system.xml: Element 'resource': This element is not expected. Line: 7

Hi @jahicDario ,

which version of the module and of Magento 2 (2.0, 2.1; CE or EE) are you using?
Currently, I cannot reproduce this issue in our test environment with Magento 2.1 CE.

Hi @websharp
I'm using Magento ver. 2.1.3 and v2.1.0-RC3 which I installed mannualy, not with composer.

Can you remove line 7 with the resource tag from the file, so it looks like this and try again:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
    <system>
        <section id="customer" translate="label" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
            <group id="bitExpert_ForceCustomerLogin" translate="label" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
                <label>bitExpert Force Customer Login</label>
                <field id="enabled" translate="label comment" type="select" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
                    <label>Enable Module</label>
                    <comment>Configures if the module is enabled</comment>
                    <source_model>Magento\Config\Model\Config\Source\Yesno</source_model>
                </field>
                <field id="url" translate="label comment" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
                    <label>Target URL</label>
                    <comment>Configures the target for redirecting, if whitelist rules do not match</comment>
                </field>
            </group>
        </section>
    </system>
</config>

When I remove line 7, Configuration page is opened but there is no Force Login tab. I also compare system.xml against vendor/magento/module-config/etc/system_file.xsd and it says that there is a problem with resource.
Here is xml and xsd.
forceLoginXml.tar.gz

I get no XML validation issues with or without removing the resource tag. I used multiple external XML validators and the in-built PHPStorm validation with the XSD resolution by using bin/magento dev:urn-catalog:generate .idea/misc.xml

You may try this example

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
    <system>
        <section id="customer" translate="label" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
            <resource>BitExpert_ForceCustomerLogin::bitexpert_force_customer_login_manage</resource>
            <group id="bitExpert_ForceCustomerLogin" translate="label" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
                <label>bitExpert Force Customer Login</label>
                <field id="enabled" translate="label comment" type="select" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
                    <label>Enable Module</label>
                    <comment>Configures if the module is enabled</comment>
                    <source_model>Magento\Config\Model\Config\Source\Yesno</source_model>
                </field>
                <field id="url" translate="label comment" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
                    <label>Target URL</label>
                    <comment>Configures the target for redirecting, if whitelist rules do not match</comment>
                </field>
            </group>
        </section>
    </system>
</config>

When I copy that in my system.xml, again page is loaded but there is no Force Login tab.

[der-workfloh]

Did you enable the module by running bin/magento module:enable bitExpert_ForceCustomerLogin?

[jahicDario]

Yes I have. Module is enabled and I can even see under customer "Force custoimer login", but it's not clickable, probably because it has to be enabled under "Force login".

[der-workfloh]

Are you accessing the backend as a fully qualified administrator? Or are you using an administrative user with custom ACL settings?

[jahicDario]

Yes, I'm accessing as first user, fully qualified administrator. I'm not sure what you mean by custom ACL settings?

[jahicDario]

I don't know how and why, first time when I was installing module with composer I was getting some version mismatch error. Now I tried again and it worked. If I somehow reduce problem again, I will write here.
Thanks for fast answers.
