Hello, Charalith,
The problem is caused by your changes in the parent theme.
It is not recommended to edit the parent theme at all because your changes will disappear after the theme update, the child theme should be used instead.
Please check the Private Content area
You need to transfer all your changes to the child theme, as they will be lost when updating. Please read the following articles for more information – https://woocommerce.com/posts/why-child-themes-matter/ https://developer.wordpress.org/themes/advanced-topics/child-themes/ https://xstore.helpscoutdocs.com/article/32-child-theme https://www.wpbeginner.com/wp-themes/how-to-create-a-wordpress-child-theme-video/
Download the child theme archive from this page – https://www.8theme.com/downloads/
Go to Appearance > Themes > install and activate the child theme.
Please note that the child theme does not inherit the theme options of the parent theme, if you enable the child theme, you need to import options from the parent theme.
Go to Theme Options (when the parent theme is activated) > Import/Export > download the export file. After that activate the child theme > go to Theme Options > Import/Export > import your options and reload the page without saving! Save options only after reloading. Check your site after that, and use the child theme.
Have you made any changes to the XStore Core plugin?
Kind Regards,
8theme team
