SCC - License Key Activation Problems

Created by Mike B, Modified on Sun, 14 Apr 2024 at 05:01 PM by Génesis Gómez

Problem #1 - License Already Used
Deactivate the Current Licence

If you're getting an error message saying you have no activations left. The first step is to log into your Member's Portal and deactivate the current license.

1. Login into
 Member's Portal - License Area. 
2. Deactivate (delete) any licenses you see on the domain you're using. Or, delete any licenses of old domains you don't use anymore.
3. Try to activate your license within the plugin, again.

Problem #2 - Error Code During Activation

We have some issues with our activation server that can be solved by, first pressing the deactivate button (with your serial in the input box), then pressing the activate button again.
Once you have the green check-mark, you are good.

Please refresh the activation license on our server by pressing the deactivate button then press the activate button again.

Note: Most common problems are #1 and #2.

1. Coming Soon / Maintenance Mode plugin

If you are using a coming soon or maintenance mode plugin, it’s likely that license keys will not be able to be activated, since the coming soon / maintenance mode plugin will block the requests. To resolve the issue, simply deactivate the maintenance mode or the coming soon plugin. If you need to leave it active, deactivate it temporarily to test the license key activation process and then reactivate the plugin.

2. Something else may be blocking your website from connecting to ours to verify your license

If you’re still unable to activate your license key on your site then it’s likely that something on your site/server is blocking the connection from your site to ours. 99.9% of our customers are able to activate their licenses without a problem, but for a select few people there seems to be a problem activating, usually due to a security setting on their server.

You are usually able to solve the problem by having their hosts add our website IP address to their outgoing firewall. Your host may have an IP-defined outgoing firewall in place on their server and so adding our site to it will then hopefully allow you to activate your license key successfully. Try asking your web host to add our site to their outgoing firewall:

  Ask your hosting to WHITELIST THIS IP  

Website URL:
IP Address:

3. Development/staging sites

For development purposes, you can activate a license key on a development/staging site without it using up a “site” on your license. This allows you to have the license key activated on both a development site and a live site. The license can be activated on the following development URLs in addition to your live site:


4. iThemes Security plugin

The iThemes Security plugin is known to have a setting that can cause this issue. The setting is called “Filter Suspicious Query Strings in the URL”

To resolve the issue, simply disable the “Filter Suspicious Query Strings in the URL” setting. If you’re not using iThemes Security, it will be named something different, though similar.
