Hello @kenny98 ,

Thank you for your message and apologies for our delayed response!

We have had some issues with our system that were not redirecting the messages to our inbox properly and that is why we missed yours.

Now coming back to the issue at hand. From what I can see you are not using the latest version of the theme however, I don’t think that is the problem here.

The problem might be related to an old issue that we had with the contact component that I see is used in your instance.

Before proceeding please make sure to backup your website.

That being said, can you please download and install this plugin? https://gist.github.com/vytisbulkevicius/9908c640793001947f7671cf58163cb6

Afterward, check if the customizer is working. If it does – deactivate and delete the plugin. Then you should be able to update the theme and use the customizer.

Please note, that this plugin will delete the contact component and you will not be able to use it anymore in the free version as it is now part of the PRO components. Although you will lose this component, you will be able to use the rest of the theme as normal.

Thank you for understanding and please let us know if this worked for you!
