Hello, Adeel Khan,
We identified an issue with the file “optimization.php” from your theme located at /wp-content/themes/zainfurniture/framework/features/optimization.php, which was different from the original file from the theme located at /wp-content/themes/xstore/framework/features/optimization.php. We have now corrected this.
If you rename the folder containing the parent theme, please make sure that all the files in the renamed folder correspond to the files of the current version of the theme.
Kind Regards,
8theme team
