Unable to update WordPress Table Rate Shipping plugin. Error message - Forbidden | Access to this page is forbidden

Hi @highdesign,

If you purchased the plugin from Envato market then to get auto-update features you can use Envato Market WordPress Plugin. This plugin helps customers receive updates to their premium WordPress Themes & Plugins purchased through Envato Market (ThemeForest & CodeCanyon).
you can download the plugin from here:

otherwise you can download the update version from Envato Market Downloads page and update manually using ftp.

Note: Better to keep a full backup before doing the update.
