As you may know, Visual Composer plugin is included to some of our themes. Your wordpress admin may offer to update it and ask for the licence key.
If you have ever purchased/downloaded Visual Composer Plugin, you were supposed to receive a licence key for it. If you do have this key, but it says it’s invalid, you will need to contact plugin’s author/developer to find out what is going on. We would be more than happy to do that for you, but it’s prohibited to share your key.
If you are trying to insert the key/purchase code you got after buying our theme – this will not work.
We need to explain that since you didn’t purchase Visual Composer plugin itself, you will not be able to update it on your own. But no worries, you still will receive plugin updates on regular basis included to our theme updates. We have no rights to share the purchase code, however we can provide the updates to our clients.
