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.
You can update the plugin in Appearance > Install plugins. Do not update the Slider Revolution now as the theme files contain the old version which is with the bug. We shall release our updagte and add the recent Slider Revolution version.
Upload Slider Revolution from the forum profiles and upload, install and activate 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.
Best Regards
