Hello,
WPBakery Page Builder and Revolution slider come bundled with our theme but they can’t be activated with our purchase code. Actually, you don’t need to do this. Only in case you want to get free premium support from its author, you can purchase it from Codecanyon. But it is not necessary since we will always provide you with the latest updates in Appearance > Install plugins.
If you have any problems (these problems are often caused by the host security or size max size limitations) you can upload the recent version of the plugins from this forum profile and or install via Dashboard > Plugins or FTP.
1. Make the full backup of your site.
2. Deactivate and delete the current version.
3. Upload the new version from your portfolio on this forum.
4. Upload and install.
We shall include the recent version in to the next update and you will be able to update in Appearance > Install plugins.
Best Regards
