I hope you are well today and thank you for your question.
I logged in to your site using shared credentials but the shared user doesn’t have sufficient privileges to troubleshoot it.
Could you please temporary make the shared user as an admin so that i can troubleshoot it?
The issue is fixed in the below latest version of theme so please update your theme.
Please login to access this file
You can update it by either deleting existing theme and then install latest theme version of it or use the following plugin to update the theme.
After activating the above plugin just install the downloaded theme on your site.
You won’t lose your site content after updating the theme but for safer side you can take backup of your site before updating the theme.
