I'm mainly a Drupal guy, I have a simple WP plugin, however, when I try to update it by uploading a new version via zip file I get Code: Unpacking the package… Installing the plugin… Destination folder already exists. /web/xxxxxxx/wp-content/plugins/xxxxxxx/ Plugin install failed. If I delete the plugin and install the new version, all is good. Any suggestions on how I can make this update either via a new .zip upload of via an update URL? I can update the install manually, but want to make it easy for the customer to update using just the WP admin page.
