Hi @Devuser34,

I hope you are well today and thank you for your question.

I visited your shared site and got the following error and you can see in the error it is caused by WPML plugin file and not theme.

Fatal error: Uncaught Exception: Error upgrading schema for table "icl_languages": in /wp-content/plugins/sitepress-multilingual-cms/inc/upgrade-functions/upgrade-3.3.7.php:54

We only provide here theme related support and not plugin. Please see here https://themeforest.net/item/jevelin-multipurpose-premium-responsive-wordpress-theme/14728833/support

Best regards,
