[VDM] Van der Meer errors

While using our Van der Meer plugin you can encounter an error. Here I will explain what the errors mean and how you can solve them.

Authorization errors

One of the first steps in setting up the Van der Meer WooCommerce plugin is authorizing your Van der Meer account with WooCommerce. However, during this process, you can experience errors. We have stated them below including the solution.

Error message	Screenshot	Cause	Solution
Shop is not registered	Screenshot	1) The permalinks are set on Plain 2) There is no valid SSL certificate problem installed. You might see an error like: cURL Error: SSL certificate problem: unable to get local issuer certificate. 3) The logs show: Response body has an invalid JSON.	1) Go into your WordPress dashboard to Settings > Permalinks and configure your permalinks to anything but Plain. Try again to authorize. 2) Activate and install an SSL certificate via your hosting provider and try again. 3) This can have 2 different solutions. It is either related to the permalinks setting also or access to the WooCommerce REST API is blocked by a firewall, server, or hosting provider. 3.1) Go into your WordPress dashboard to Settings > Permalinks and configure your permalinks to anything but Plain. Try again to authorize. 3.2) Check with your hosting provider what is blocking the WooCommerce REST API and make sure it will get unblocked. Try again to authorize, once this is done.
Woosa secret key is invalid	Screenshot	You have changed domains, database or cloned your webshop.	You can find the Woosa secret key via WooCommerce > Settings > General and scroll all the way down. You will notice that this field is disabled and you can’t edit it. However, that field probably has the wrong secret key stored. The only way to solve this is by Submitting a Ticket including access to your WordPress dashboard. Our Support Desk will be able to solve this within minutes.

It might happen that after these steps you will receive a new error during the authorization: Woosa secret key invalid. Please read the solution for this error above.
