We were able to reproduce this in our testing environment once. I happened when WordPress failed to create the cache or log folders.

Please create them manually, this will solve the issue. You will need to create the following structure inside the wp-content folder.

wp-content/wpmvc/log
wp-content/wpmvc/cache

This was most likely caused by cache folder permissions, we have moved logs/cache to another path (inside wp-content) to avoid this type of issues.

If you are getting a “No ‘Access-Control-Allow-Origin’ header is present on the requested resource.” sounds that you are having an issue with the way your wordpress setup is configured to handle requests headers.

We would recommend you to take a look at how you can modify them since we ain’t modifying them at all in the plugin.

Usually this can be fixed by modifying the .htaccess file on your wordpress root. Here is an article that explaing this better:

Plugins like W3 Total Cache may also be affecting the CORS origin issue.

So far, no reported issues with WooCommerce 3.5.1

Also any option to see license activations in admin dashboard

Using the WordPress.org version no. But with our paid extension yes (here), it comes with manage pages to view and edit customer license keys from the admin dashboard.

is there a way to check license key if it’s valid or not? I mean the key which is not activated yet, just to see if the entered value is a valid key or not.

With the api no, since the activation endpoint already does the process and there is not need to do a previous request just to validate.

But if you wish to do this, you can accomplish this by using the LicenseKey model class:

<?php
use LicenseKeys\Models\LicenseKey;

if ( LicenseKey::find( '[a-customer-license-key]' ) ) {
    // FOUND
} else {
    // NOT FOUND
}

a query to db for retrieving that information with a custom plugin?

You can always use the model explained above to query the db, the model uses the FindTrait.php, which you can review, to provided proven query functionlity.

An example:

<?php
use LicenseKeys\Models\LicenseKey;

$license_keys = LicenseKey::fromOrder( $order_id );

If you wish to extend the query functionality to add custom queries you can do this bu creating you own model that extends from the existing one:

<?php
use WPMVC\MVC\Collection;
use LicenseKeys\Models\LicenseKey as Model;

class MyLicenseKey extends Model
{
    public static function all()
    {
        $license_keys = new Collection;
        // TODO QUERY CODE
        return $license_keys;
    }
}

Have you changed hosting? Which hosting are you using?

The issue is related to the function used to define wordpress root folder and where is the plugins usually installed, which should be under folder wp-content, but yours looks to be different.

We would love to know more about your setting in order to make proper changes and fix this issue on your setup.
