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.
