Updating theme

Hi monicasutrisna
About update themes issue, there's no way. You have to update manually by yourself. To update Kute theme:
Step 1: Backup your site( Include codes + Database)
Step 2: From the dashboard>>Appearance>>Theme, you need to activate the default template( Ex; Twenty Seventeen theme)
( you can refer this document, it's the same http://test.kutethemes.net/koolshop_doc/#mazanoupdate)
Step 3: Click on Kute Boutique and then click Delete( look down in the right). NOTE: DO NOT delete the Kute-Boutique-Child
Step 4: Return the dashboard choose Plugins then deactive the Boutique Toolkit, Slider Revolution, WPBakery Visual Composer and delete them.
Step 5: Return the Appearance menus choose Theme>>Add New>>choose your latest theme version>>Install
Step 6: Return the Plugins menus>>New>>and choose the Kutes Toolkit (Slider Revolution, WPBakery Visual Composer plugins are the same)>>Install>>and activate them.
Please do it and let me know.
