This is the default behaviour for WordPress. But there is a plugin called “Easy theme and plugin upgrades” that handles this for plugin and template updates: https://de.wordpress.org/plugins/easy-theme-and-plugin-upgrades/ After installing the plugin, you can just upload a new zip and it wont’t install another plugin/theme instance.

Try to clear the buffer before returning your AJAX response. public function request_handler() { $post = $_POST; $data = $post[‘data’]; $this->zip_file(); ob_clean(); echo json_encode($data); die(); }
There is no way to prevent the free distribution of your theme. You could make it harder by selling a copy that is restricted to a license key and a salted hash of the domain. But even if you put the code for this in a pre-compiled script it will be possible to get around … Read more
