See Solution 3

Explain

We’ve just moved to Magento 2, the activation URL changed. Sometimes you cannot activate correctly.

Solution 1

Step 1: Upgrade Mageplaza Core

You should upgrade mageplaza core module to version 1.4.3 or greater.

Update to v1.4.3

composer update mageplaza/module-core:1.4.3

Update to Latest version

composer update mageplaza/module-core

Step 2: Activate again

Fill Name and email to Activate again.

Solution 2

If you still cannot upgrade to module core v1.4.3, let try this solution:

Open composer.json file in your root folder (not module-core/composer.json).

Change to:

        "mageplaza/module-core": "1.4.3",

Then run update command line:

composer update mageplaza/module-core

Result:

Solution 3

You server may cannot to our License Server, that why it cannot activate.

So you need to Map hostname to a IP address:

Open /etc/hosts and add this line:

198.199.79.159   dashboard.mageplaza.com

以上係Google的方法，但我試過之後都唔得，最後只能改code，如下 etc/config.xml

        <module>
            <type>1</type>
        </module>

        <module>
            <type>0</type>
        </module>
