Hi Bartek,
Thank you for buying our theme. We hope it will meet all your expectations! 🙂
I think your issue is probably due to a conflict with a third-party plugin or a missing update.
First of all, could you deactivate all plugins that have not been installed with your theme during its setup and all existing custom PHP code snippets please? And then, could you confirm me that the issue is still persisting please?
Then, please make sure that you have the latest theme version and that all recommended plugins are up-to-date. To update your theme, you can download and install the Envato Market plugin (https://envato.com/market-plugin/) on your WordPress site. Once the plugin is installed and activated, go to “Envato Market” in your admin menu and follow the instructions under “Activate Envato API Connection”.
When this is done, you will see your purchased themes under the “Themes” tab and you should be able to update your theme from there by clicking the “Update available” button.
Finally, you could also consider clearing all activated caching system as well as your browser cache before investigating any further. If you want to read more on what browser cache is and how to clear it, here is an article that might help you: How to Clear Internet Cache in Every Major Browser.
We’re waiting for your feedback.
Cheers,
