My license key does not work

There could be situations when you try to register your website using your SliceWP license key, but instead of everything running smoothly, you’re seeing an error.

There are multiple instances where this can happen. Here’s a list of the errors and what you need to do to solve them.

This error appear if the license key you’ve inputted does not exist on our servers. Please make sure that the key you are using is the correct one from your SliceWP account.

If you don’t have a SliceWP license, you can purchase one from our pricing page.

The type of license you have determines the number of websites you can have SliceWP registered on. If you already have SliceWP installed and registered on other websites, you may have reached your maximum website cap.

You can view all of the registered sites you have in your SliceWP account.

If you’ve reached the cap, you have a couple of options:

  1. Upgrade your license to a higher tier to raise your license limit cap.
  2. Go to SliceWP > Settings > General (tab) > Register Website (section) on one of the other websites you have SliceWP installed, and click the “Deregister” button. You can then register another website with this license key. If the other website where you’re using SliceWP no longer exists, then you can also deregister the license key from that website from your SliceWP account.

This error appears when your license key has expired. If you don’t have a lifetime license, then your license is set to expire if you disable automatic renewals or if the renewal payment for your subscription fails.

You can reactivate your license at anytime by manually renewing it from your SliceWP account.


  • cURL error 28: Operation timed out after 10001 milliseconds with 0 bytes received
  • cURL error 28: Failed to connect to port 443 after 10001 ms: Couldn’t connect to server

These types of errors have multiple causes. In general, something is blocking the connection between your website and ours, so your license key cannot be validated by our server.

Here are the most common causes for these errors:

  • Do you have a security plugin active? Some WordPress security plugins may interfere with external requests being made by other plugins. To check if this is the case, please deactivate all your plugins (except for SliceWP) and enter your license key again. If it works then one of your plugins is blocking the external request – probably your security plugin.
  • Are you using CloudFlare? If you are using CloudFlare as a CDN, Caching Layer or SSL provider then we recommend you configure CloudFlare to bypass cache for all URLs that contain this string: /?edde_api_action. CloudFlare support will be able to help you with this if needed.
  • Is your cURL timeout limit high enough? Please contact your hosting company or server administrator. Ask them to increase the cURL timeout limit.
